Whether sinners who are going to be baptized are bound to confess their sins?

❌ Objection 1 : It seems that sinners who are going to be baptized are bound to confess their sins. For it is written (Mt. 3:6) that many "were baptized" by John "in the Jordan confessing their sins." But Christ's Baptism is more perfect than John's. Therefore it seems that there is yet greater reason why they who are about to receive Christ's Baptism should confess their sins.

❌ Objection 2 : Further, it is written (Prov. 28:13): "He that hideth his sins, shall not prosper; but he that shall confess and forsake them, shall obtain mercy." Now for this is a man baptized, that he may obtain mercy for his sins. Therefore those who are going to be baptized should confess their sins.

❌ Objection 3 : Further, Penance is required before Baptism, according to Acts 2:38: "Do penance and be baptized every one of you." But confession is a part of Penance. Therefore it seems that confession of sins should take place before Baptism.
