Sermon prep
— 14 terms about preparing and preaching
- Exegesis
- Drawing meaning out of a biblical text on its own terms — historical context, grammar, original languages. The opposite of reading your conclusions into the text.
- Eisegesis
- Reading your own ideas into the text instead of letting the text speak. The mistake exegetes try hardest to avoid.
- Expository preaching
- A sermon driven by a specific biblical passage, working its meaning out for the congregation. Usually one passage, one Sunday.
- Topical preaching
- A sermon organized around a theme — marriage, anxiety, generosity — that draws on multiple passages. Different posture than expository; both are legitimate.
- Lectionary
- A predetermined yearly cycle of Scripture readings followed in many liturgical traditions (Anglican, Lutheran, Catholic). Preaching follows the calendar, not the pastor's mood.
- Manuscript preaching
- Preaching from a fully written-out script. Tighter than notes; harder than memorization.
- Sermon outline
- The skeleton of a sermon: text, big idea, three or four movements, and the close. Most working pastors write the outline before the manuscript.
- The big idea
- The one-sentence point a sermon makes. If you can't compress your sermon to a sticky note, you're not done structuring.
- Homiletics
- The art and discipline of preaching. Includes structure, delivery, illustration, and rhetorical craft.
- Sermon series
- A sequence of sermons (4-12 weeks) on a related theme, book, or biblical character. Most growing churches preach 70% in series.
- Pericope
- A self-contained passage of Scripture, usually one story or argument. The unit most expository sermons work from.
- Sermon coach
- Tool or person that gives homiletic feedback on a recorded sermon — flagging filler words, weak openings, pacing issues, and unclear structure.
- Memorization (sermon)
- Preaching without notes. Distinct from "winging it" — true memorization involves repeated rehearsal of a manuscript.
- Sermon rehearsal
- Practicing the delivery of a sermon before Sunday — usually two passes, timed. The most-skipped step in working pastor prep.
AI in ministry
— 12 terms about machine learning in church work
- Barnabas
- Pastor Center's pastoral AI assistant. Trained on your church's data, prompted with your theological tradition. Helps outline, edit, follow up, and search your own preaching history.
- Deep Sermon Research
- A 23-agent research engine that produces a 23,000-word research report on a passage in roughly 3 minutes — exegesis, original languages, cross-references, illustrations, and historical context.
- Theological guardrails
- Constraints inside an AI system that prevent it from generating content contrary to a specified theological tradition. Pastor Center tunes 14 of these.
- Hallucination
- An AI confidently inventing a fact — like a fake Bible verse or a non-existent commentary citation. Purpose-built tools are designed to refuse this; generic AI is not.
- Prompt engineering
- The discipline of crafting AI inputs to get reliably good outputs. The behind-the-scenes work that makes specialized tools like Pastor Center work.
- Sermon writer (AI)
- An AI-assisted writing surface that helps a pastor draft, tighten, and revise a sermon manuscript — never to replace authorship, only to accelerate it.
- Agentic AI
- AI that takes multi-step actions — drafting an email, scheduling, following up — rather than just answering a question. Ministry AMS uses this.
- Retrieval augmented generation (RAG)
- An AI technique that grounds answers in retrieved source documents (e.g. real commentaries) rather than relying on memory. Reduces hallucination.
- Voice training
- Adapting an AI's output style to a specific pastor's manuscript voice, vocabulary, and rhythm. Pastor Center learns yours after ~5 sermons.
- AI citation
- A reference to the specific source backing an AI claim — e.g. "Carson on John, PNTC, 1991, p. 384." If a tool can't cite, don't trust it.
- llms.txt
- An emerging file convention (similar to robots.txt) that signals to AI crawlers how to read and cite your site. Pastor Center publishes one.
- GEO (Generative Engine Optimization)
- The discipline of optimizing content to appear in AI search engine answers (ChatGPT, Perplexity, Claude, Google AI Overviews) — distinct from classical SEO.
Church operations
— 12 terms about running a church
- ChMS
- Church Management System — software that holds member data, scheduling, giving. Planning Center, Breeze, Subsplash, CCB, Rock RMS, MinistryPlatform are major examples.
- Ministry AMS
- Pastor Center's AI agent that runs on top of your ChMS — handling follow-up, scoring group health, and surfacing volunteer pipeline issues.
- Connection card
- A physical or digital form first-time guests fill out. Hybrid (paper + QR) typically out-performs single-channel by 2× capture rate.
- First-time guest
- Someone visiting your church for the first time. The 48-hour follow-up window after their visit is the highest-ROI ministry act of the week.
- Assimilation
- The process of moving a new attendee from visitor → connected member → engaged volunteer. Most churches lose 60% of guests at the first step.
- Volunteer pipeline
- The system that moves members through invitation, equipping, deployment, and multiplication into ministry roles.
- Small group health
- A set of metrics (attendance, leader reporting, member engagement) that signals whether a small group is thriving, drifting, or dying.
- Disconnected member
- A member who hasn't checked in or attended in 4-6+ weeks. The window where intentional outreach prevents quiet departure.
- Multi-site
- One church with multiple physical locations (campuses). Sermon content typically shared via video or simulcast; pastoral teams local.
- Bivocational pastor
- A pastor with a non-ministry day job in addition to their pulpit. Historically the default for most pastors worldwide; increasingly common again in 2026.
- Church plant
- A newly-launched church, typically 0-3 years old. Usually a small launch team, scaling from 20 → 200 attendance over 18-24 months.
- Annual planning
- The off-site week (usually November) where a church team plans the coming year's sermon series, calendar, budget, and major initiatives.
Theology & tradition
— 12 terms about doctrine and frameworks
- Orthodoxy
- Right belief — typically the historic essentials of Christian faith as articulated in the early creeds (Nicene, Apostles', Chalcedonian).
- Orthopraxy
- Right practice — the lived embodiment of orthodox belief. Some traditions emphasize this more strongly than orthodoxy.
- Reformed
- A theological tradition emphasizing God's sovereignty, election, covenant theology, and the Westminster/Heidelberg confessions. PCA, OPC, EPC, and others.
- Wesleyan / Methodist
- A tradition emphasizing free grace, sanctification as process, and methodical Christian discipleship. UMC, GMC, AME, Free Methodist, and others.
- Pentecostal / Charismatic
- A tradition emphasizing the active gifts of the Spirit — tongues, prophecy, healing — and ongoing direct work of the Holy Spirit. AG, Foursquare, COGIC, Vineyard, and others.
- Anglican
- A liturgical tradition with deep roots in the English Reformation. ACNA, TEC, and various other jurisdictions globally.
- Baptist
- A tradition emphasizing believer's baptism, congregational governance, and local-church autonomy. SBC, CBF, AB, and many independent churches.
- Logos
- Greek for "word" — used in John 1 to identify Christ. Also a popular Bible software product.
- Hesed
- Hebrew for "covenant love" — sometimes translated as "steadfast love" or "loyal love." Untranslatable in one English word.
- Shalom
- Hebrew word usually translated "peace" but carrying connotations of wholeness, flourishing, and right relationship.
- Eschatology
- The study of last things — Christ's return, judgment, resurrection, new creation. Traditions disagree significantly on details.
- Liturgical calendar
- The yearly rhythm of worship seasons — Advent, Christmas, Epiphany, Lent, Easter, Pentecost, Ordinary Time. Followed in liturgical traditions.
Spiritual gifts & placement
— 10 terms about gifts assessment and ministry placement
- Spiritual gifts
- Specific abilities given by the Spirit to members of the church for the building up of the body (1 Cor 12, Rom 12, Eph 4). Lists vary; the principle is consistent.
- Spiritual gifts assessment
- A short inventory (20-120 questions) that surfaces a member's likely gifts. Pastor Center's runs 112 questions in roughly 20 minutes.
- DISC assessment
- A personality framework (Dominance, Influence, Steadiness, Conscientiousness) commonly paired with spiritual gifts assessments. Helps with team dynamics, not just gifting.
- Gift-based ministry
- The practice of staffing ministry teams based on member gifts and personality fit rather than warm-body availability. Increases retention significantly.
- SHAPE
- An acronym (Spiritual gifts, Heart, Abilities, Personality, Experiences) made popular by Saddleback Church for guiding members into ministry. One of several frameworks; the principle is similar.
- Volunteer retention
- The percentage of volunteers still serving 90 days after they started. Gift-based placement typically lifts retention from ~40% to 70-80%.
- Multiplication (volunteer)
- The point at which existing volunteers recruit new volunteers without staff intervention. Healthy churches hit ~25% multiplication rate annually.
- Body life
- The relational and functional health of a church community as the "body of Christ" — used to describe whether members are actually using gifts in service.
- Ministry placement
- The act of moving an assessed member into a specific volunteer or service seat in the church. Most assessments stop short of this; Pastor Center automates it.
- Equipping
- The brief structured onboarding that turns a willing member into an effective volunteer. Usually a 20-minute video, a one-page reference, and a buddy for three shifts.
Growth & church media
— 10 terms about social, video, and reach
- Sermon clip
- A short (15-90 second) excerpt of a Sunday sermon, captioned and formatted for social platforms. Most growing churches generate 15-20 per sermon.
- Vertical aspect ratio
- 9:16 format — the orientation of TikTok, Instagram Reels, and YouTube Shorts. Essential for mobile-feed discovery.
- Hook moment
- A surprising or quotable sentence from a sermon that makes a scroller stop. The 15-30 second clip type that performs best on social.
- Auto-captioning
- Burning text captions directly onto video clips. Required for sermon clips because most social viewers watch with sound off.
- The clip flywheel
- The compounding loop of posting consistent sermon clips → discovery → first-time guests → more clips. Takes ~90 days to spin meaningfully.
- Church graphics
- Custom visuals for sermon series, social posts, slides, and bulletins. Increasingly AI-generated; should still match brand standards.
- Brand kit (church)
- A defined set of colors, fonts, logos, and tone-of-voice rules a church applies consistently. Worth building before scaling media output.
- Sermon discipleship material
- Discussion guides, devotionals, and small-group questions derived from each Sunday's sermon. Often auto-generated from the manuscript.
- Sermon repurposing
- Turning one sermon into multiple content pieces — clips, devotionals, social posts, study guide. A 6-hour sermon yields 12+ artifacts if done well.
- Return rate (first-time guest)
- The percentage of first-time guests who attend again within 4 weeks. Healthy churches run 30-40%. Without active follow-up, rates collapse to 10-15%.
Pastoral health
— 10 terms about durability in ministry
- Burnout
- A clinical condition of emotional, physical, and motivational exhaustion. The leading reason pastors leave ministry.
- Sabbatical
- An extended (4-12 week) intentional pause for rest, restoration, and recalibration. Often taken every 5-7 years; rarely taken as scheduled.
- Compassion fatigue
- The depletion that comes from sustained empathetic engagement with suffering. Specific to caregivers, pastors among them.
- The 8pm rule
- A boundary practice: no church work after 8pm. Protects family, sleep, and long-term ministry durability.
- Notification fatigue
- The chronic stress of always-on phone alerts. A common but reversible pastoral health hazard.
- Pastoral counseling
- Brief, spiritually-framed counseling provided by clergy to congregants. Distinct from clinical therapy; complementary, not substitutive.
- Soul care
- The disciplined attention a pastor gives to their own spiritual, emotional, and physical formation. The non-negotiable that's most often skipped.
- Spiritual direction
- A formal relationship with a trained guide who helps a pastor discern God's work in their life. Distinct from therapy and from mentoring.
- Off-ramp Sunday
- A pre-planned Sunday where someone else preaches — a guest, a staff member, a visiting pastor. Healthy years include 4-6 of these.
- Ministry durability
- The capacity to preach, pastor, and lead for 20+ years without breaking. Built more by rest disciplines than by hustle.
