Baptismal life is not left to private resolve alone; the churches that teach it build public moments into the calendar that renew the promises made at the font. The clearest is the Easter Vigil, where the whole congregation, not only those being baptised that night, renews its baptismal vows: rejecting evil, professing the creed clause by clause, and being sprinkled with water blessed at the same service. Confirmation completes the initiation begun at baptism in traditions that separate the two, understood as the sealing of the Spirit already given, and in others it stands as a personal ratification of vows a godparent spoke on the candidate's behalf as an infant. Godparents themselves are part of the structure rather than an ornament: they undertake at the font to support the child's formation and are asked, in many rites, to renew that undertaking alongside the candidate at Confirmation.
Adult converts pass through an extended catechumenate, in the Catholic Rite of Christian Initiation of Adults stretched across a full liturgical year and marked by public scrutinies before the community, so that baptism itself becomes the climax of a long formation rather than a single ceremony. Anniversaries of baptism are kept in some traditions much as a birthday is, and a person's baptismal name, chosen or received at the font, can outlast every other name they are given. What unites these observances is the same logic the daily practice runs on: a status conferred once needs occasions built into the church's year to keep it in view, or it recedes into a fact about the past rather than a claim on the present.
