Q. 3. How doth it appear there are three persons, and no more?
A. First, From Christ's baptism; Mat. 3:16, 17. And Jesus, when he was baptized, went up straightway out of the water, and lo, the heavens were opened unto him, and he saw the Spirit of God descending, like a dove, and lighting upon him; and lo, a voice from heaven, saying, This is my beloved Son in whom I am well pleased.
