adnauseum: Repentance certainly is necessary! This is the teaching of the Church, not only Protestants. How can you obey the commandments without repenting of your sins? To repent means to experience sorrow for one’s sins and to turn your life around. By turning it around, you begin to obey the commandments.
As well, without repenting of one’s sins you can NOT be forgiven of them. This is the clear teaching of the Church. We often refer to repentance as ‘contrition’ in Catholicism. If one goes to confession and is not repentent of the sins one is confessing, the sacrament is null and void. Plain and simple.
Remember what Jesus preached: “Repent!”
Scripture makes it clear that it is necessary to repent of your sins to achieve eternal salvation. That is what God calls us to. That is the first step (well second, after believing). See Matt. 3:2, Matt. 4:17, Matt. 11:20, Matt. 21:32, Mk 1:15, Lk 13:1, Lk 13:3, Lk 13:5, Lk 15:7, Lk 16, Acts 2:38, Acts 3:19, Acts 8:22, Acts 26:20, Rev. 2:5, Rev. 2:16, Rev. 2:21, Rev. 2:22, Rev. 3:3 and 19, Rev. 9:20, Rev. 9:21, Rev. 16:9, Rev. 16:11.
Baptism, like confession, is also null and void if the person has not repented of his (or her) sins prior to receiving the sacrament. (This, of course, does not apply to children who have no need to repent). Peter declared, in Acts 2:38: “Repent and be baptized…”
