[At Jesus’ baptism] then we have the Trinity presented in a clear way: the Father in the voice, the Son in the man, the Holy Spirit in the dove. This ineffable Divinity, abiding ever in itself, making all things new, creating, creating anew, sending, recalling, judging, delivering, this Trinity, I say, we know to be at once indescribable and inseparable.

—Augustine, Sermon 2.1-2
