What?! No. Sacraments are not a good work to earn God's favor. Sacraments are a visible sign of His grace. The church has always taught that baptism is necessary. The sacraments are the Avenue that God gave to humanity to encounter Him.

Of course the caveat is that the sacraments are the Avenue that God gave us. He is not constrained by them and we can hope that He saves those who have no access to His sacraments as He did with those who lived before Christ. But God is free, but we are bound by the commands he gave us. I am not "cherry-picking" verses, those are some of the verses that the church herself references.
