Notice that the authority in that statement, is you.
We believe that Jesus Christ gave the Church authority to teach all that He commanded.
True. But Baptism imparts the Spirit.
Acts 2:38 Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
Baptism is an outward representation of what has happened internally in the heart, it does not cause the heart to change but is a way we show a changed heart.
Baptism is an outward representation of what is effected, or caused, in the heart (i.e. soul) when the water washes the body.
Something happens to the righteous man when the water washes his body. That something is caused by God.
It sounds like Catholics belief in irresistible grace (at least initial grace) because God works through the waters of baptism to dispense grace.
Not quite. Remember what Jesus said in Mark 16:16. He who believes and is baptized will be saved. He who does not believe, will be condemned.
For non-Christians, justification will occur at the Judgment. Much like the Jews had to await justification in Abraham’s bosom (Heb 11).
But for Christians, justification occurs in the Sacraments. When we submit to the Sacraments, beginning with Baptism, we are judged. God looks into our hearts and if He sees righteousness there, He declares us justified and, unlike Abraham, He makes us righteous, by washing us with the grace of the Holy Spirit.
But, if God looks into our hearts and sees that we are not righteous, but feigning belief. If He sees that we are not inclined to do His will, we are committing sacrilege and as the Scripture says about the Eucharist, “many of you are dying and have died” because of this:
1 Corinthians 11:29
For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
That is why Scripture also says:
1 Peter 4:17
For it is time for judgment to begin with God’s household; and if it begins with us, what will the outcome be for those who do not obey the gospel of God?
