What about confession?
What would you like to know?
Those being baptised do not need Confession, because baptism washes away all sin, original and personal.
Those who are joining the Catholic Church from other Christian denominations go to Confession before they receive Communion and Confirmation. Usually this is done a week or two before Easter.
Most of the time they would have already made their first confession before Easter Vigil mass.
The candidates, those already baptized, have gone to Confession in preparation for this night.
The catechumens, those not yet baptized, did not. Because, of course, Baptism does what it always does, cleanse us from all sin.
