Mass

Catholic & Orthodox

The Catholic worship service, centered on the Eucharist — scripture readings, a homily, prayers, and communion, in a fixed order every time.

"The Catholic Sunday service. Also Saturday evening. Also weekdays, if you're keen."

Obvious

Maundy Thursday

Holidays & Calendar

The Thursday before Easter, remembering the Last Supper — when Jesus washed His disciples' feet, instituted communion, and gave the "new commandment" to love one another. It opens the three holiest days of the year.

"The night before Good Friday: the Last Supper, foot washing, and a service that ends in silence."

Confusing

Membership

Church Life & Services

Formally joining a church — usually after a class, sometimes a vote, interview, or ceremony — as distinct from just attending.

"Officially signing up, not just showing up."

Mildly puzzling

Membership Covenant

Church Life & Services

A written statement of commitments — to attend, give, serve, live by the church's standards, and submit to its leadership — that some churches ask members to sign when they join.

"The terms and conditions of joining the church, which you actually sign."

Very confusing

Mentor

Ministry & Leadership

An older or more experienced Christian who guides someone in their faith — meeting regularly, teaching, and taking an interest in their growth.

"The person who's further along and helps you get there."

Confusing

Ministry

Ministry & Leadership

Any organized work of serving others in the church or in Jesus' name — from a food pantry to a choir to a career as a pastor. "My ministry" means the particular service someone does.

"Church work — any of it, paid or not."

Confusing

Missions

Ministry & Leadership

Christian work of sharing the faith and serving people in another culture or country — for a week (a mission trip), a few years, or a lifetime (a missionary).

"Going somewhere else to serve and share faith — a week, a year, or forever."

Mildly puzzling

Mountaintop Experience

Youth Group & Camp

An intense spiritual high — often at camp, a retreat, or a conference — when God feels close and everything is clear. "The valley" is what comes after.

"The spiritual high after camp. It fades. That's normal."

Very confusing

Campus

Church Life & Services

One church with several locations — "campuses" — often sharing a sermon by video from the main site, with each campus having its own live band and pastor.

"One church, several buildings. The pastor may be on a screen."
