Resources
Where the claims on this site actually come from, and where to check them yourself.
- Catechism of the Catholic Church (Vatican) — The primary source for everything on this site — the full text, free, from the Holy See's own archive
- United States Conference of Catholic Bishops (USCCB) — For US-specific guidance, liturgical calendar, and official statements
- Vatican official website — Papal documents, encyclicals, and council documents in their original form
This site presents Roman Catholic teaching as expressed in the Catechism of the Catholic Church and official Church documents — it does not speak for any other Christian tradition, and it is not a substitute for your own parish or diocese.
The liturgical year
The seasons that structure Catholic worship and practice across the year.
| When | What happens |
|---|---|
| Advent | The four weeks before Christmas — a season of preparation and anticipation |
| Christmas season | From Christmas Day through the Baptism of the Lord, celebrating the Incarnation |
| Lent | Forty days before Easter, marked by fasting, almsgiving, and prayer, beginning on Ash Wednesday |
| Holy Week and Easter | The most significant week of the liturgical year, from Palm Sunday through the Easter Vigil and Easter Sunday |
| Ordinary Time | The longer stretches outside the major seasons, focused on the ordinary teaching and life of Christ |
Always confirm current dates with the official source — they move.
Checklists you can work through
Before your first confession in years
- Find your parish's posted confession times, or call to ask
- Use a printed examination-of-conscience guide beforehand if it helps
- Decide face-to-face or behind the screen — both are completely normal
- You don't need to memorise the Act of Contrition — most confessionals provide a card
- Telling the priest it's been years is fine and said constantly
- Afterwards, the penance is usually small — a few prayers or an act of charity
Preparing to attend Mass for the first time
- Arrive five to ten minutes early to avoid walking in mid-procession
- Dress modestly — no specific dress code beyond that
- Follow the congregation's lead on standing, sitting, and kneeling
- Communion is for Catholics in good standing — cross your arms for a blessing instead if that's not you
- A missalette or worship aid in the pew has the readings and responses printed out
- Staying for the full Mass, including the final blessing, is customary
Common mistakes people make about Catholic teaching
Treating a parish custom as universal Church teaching
Ask whether something is defined doctrine, official teaching, or local custom before assuming it applies everywhere — the distinction genuinely matters
Assuming confession requires memorising a script
A confession guide card in the confessional covers the words; showing up honestly matters more than reciting anything perfectly
Quoting Scripture without naming a translation
Wordings differ meaningfully between translations — name which one you're using, especially in a teaching or debate context
Confusing veneration of Mary and the saints with worship
Worship belongs to God alone in Catholic teaching; honour given to Mary and the saints is a categorically different, lesser thing
Assuming Catholic and 'Christian' teaching are interchangeable
Say 'Catholic teaching holds' rather than 'Christianity teaches' when the point is specific to Catholic doctrine — many Christian traditions disagree on real points
Waiting to feel 'ready enough' before returning to Mass or confession
There's no readiness threshold in Catholic teaching — showing up itself is the step, not a reward for having resolved everything first
Glossary
The words that get used as if everyone already knows them.
Catechism
The official compendium of Catholic teaching, organized into belief, sacraments, moral life, and prayer.
Magisterium
The Church's teaching authority — the pope and bishops in communion with him — responsible for authentically interpreting Scripture and Tradition.
Dogma
A truth defined by the Church as divinely revealed and binding on all Catholics — the highest level of certainty in Catholic teaching.
Sacrament
In Catholic teaching, an outward sign instituted by Christ to give grace — there are seven.
Transubstantiation
The Catholic teaching that the substance of bread and wine becomes the body and blood of Christ at consecration, while the appearances remain unchanged.
RCIA / OCIA
The formal process by which adults become Catholic, typically culminating at the Easter Vigil.
Mortal sin
A sin Catholic teaching holds is serious enough to sever one's relationship with God, requiring grave matter, full knowledge, and full consent together.
Venial sin
A lesser sin that weakens, but does not sever, one's relationship with God.
Absolution
The priest's pronouncement in confession that forgives sin, in Catholic teaching genuinely reconciling the penitent with God and the Church.
Veneration
The honour given to Mary and the saints in Catholic practice, explicitly distinguished from the worship owed to God alone.
Nicene Creed
The statement of core Christian belief formalised at the fourth-century councils of Nicaea and Constantinople, recited at Sunday Mass.
Annulment
A declaration that a marriage, though it appeared valid, lacked something required for validity from the start — distinct from divorce.
