Also still waiting for any of you to address acts 8
8:36-37
An autumn day, the plain extending on either side, a chariot driver half-dozing, two men poring over a roll.
Having reread the passage in question, the eunuch asked Philip whether the prophet was here speaking of himself or someone else. The teaching he had had didn't let him decide this point.
Philip could hardly have found a better text to expound his topic, for his subject was Jesus. Starting with the OT texts, he had a chance to show prophecy's fulfillment in Christ's case. He spoke also of Christ's commission which he'd given to his disciples, “to teach all people groups, baptizing them in the name of God and of Jesus and of the Spirit."
While Philip was still picturing Jesus' glories, the chariot came near a pool which contained some water.
The eunuch points to the water and asks whether there would be anything in the way of his being baptized.
Philip replied that his wish may be granted if he believes.
The eunuch confesses "I trust that Christ's God's Son." A formula amounting to a confession in God.
The officer then halted the chariot, and both Philip and the eunuch went down to the water, where the latter was baptized, the method not being indicated.
When the baptism was complete, God, the Spirit, did a miracle by removing Philip from the eunich's side and out of his sight.
However, the eunich had heard the facts which enabled him to compare the OT with the New, and so he joyfully went his way.
