It has for its goal the glory of God and of Christ, and the gift of eternal life. I do not see the Bible saying anywhere that we are justified by baptism. However, according to Roman Catholicism even faith and baptism aren't sufficient in themselves for you to be saved. It says that baptism is only the first sacrament of forgiveness. Anything we do in hopes of getting or maintaining our righteousness before God.
Grace is by definition unmerited favor.
To me this is an utterly false teaching. This is the crux of the problem. Roman Catholic theology asserts that God's grace is granted through baptism and infused into a person by the Holy Spirit. This then enables him or her to do good works which then are rewarded with heaven. Not at all.
