Remembering Baptism

I have been 'baptized' twice, first by my mother and once in a Baptist church. The Baptist church baptism is the only one I have documentation for, even though it came second. Even though my mother baptized me first and would have used the Trinitarian formula, I can't actually remember it, and have no documentation. Which one should I view as my one and only baptism?

If you were baptized following the Bible’s directive of using water and the word of God, you were the recipient of a legitimate Baptism. It sounds like your second Baptism was not necessary.

Rather than focusing on differentiating between your Baptisms, I would encourage you simply to focus on the blessings of Baptism. “So in Christ Jesus you are all children of God through faith, for all of you who were baptized into Christ have clothed yourselves with Christ” (Galatians 3:26-27).
