A few texts for last night and for today.
First Tertullian describes third century practice:
Baptism is performed with very great simplicity, without pomp, without any large amount of novel preparation, finally, without expense. A person is dipped in water and is sprinkled while some few words are spoken, and then rises again; though not much cleaner, the consequent attainment of eternity is esteemed the more incredible.
Baptisms do need song. My parish uses a simple alleluia to acclaim Christ in the sacrament. What more do you need to sing someone into eternal life? If you do need a few more words, here is a favorite, from the fifth century Middle East:
Stretch out your wings, O holy church,
and greet the simple lambs
whom the Holy Spirit has begotten from the waters.
Clement of Alexandria provides a longer text than Paul quoted in Ephesians 5:14:
Awake O sleeper, and arise from the dead
and Christ shall give you light.
Light of the resurrection,
Begotten before the morning star
who gives life through his radiance.
May all the baptized shine in the radiance of the grace of Christ this day, and every day.
