1 Coríntios 1:16

The members of Stephanus’ family were the first converts in the Roman province of Achaia (1 Corinthians 16:15). It was unimportant to Paul whom he personally baptized; he was not keeping score. This is clear because he temporarily forgot that he had baptized these people. As he continued to write, the Lord brought them to mind.

"Paul casts no reflection on baptism, for he could not with his conception of it as the picture of the new life in Christ (Romans 6:2-6), but he clearly denies here that he considers baptism essential to the remission of sin or the means of obtaining forgiveness."
