The eunuch did not 'present himself to the church for baptism.

Lutero:

Have you forgotten what you said? I do. And you've been proven wrong.

The eunuch did not 'present himself to the church for baptism."

Yes, he did. This is what it means to present oneself to the Church:

Acts 8:
³⁶ And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?

He requested Baptism.

And as he headed on his way back to Ethiopia, do ya think he was packin' a priest with him with extra wafers for the trip?

He didn't have to. God sent him one:

²⁶ And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem unto Gaza, which is desert.
²⁷ And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the charge of all her treasure, and had come to Jerusalem for to worship,
²⁸ Was returning, and sitting in his chariot read Esaias the prophet.
²⁹ Then the Spirit said unto Philip, Go near, and join thyself to this chariot.
