Today's first reading is from Acts 8:26-40. The Holy Spirit inspires Phillip to stop a carriage and speak to a eunich who is reading from the Holy Scriptures. Phillip asks the man, “Do you understand what you are reading?”
The man replies, “How can I, unless someone instructs me?”
And, how can someone instruct others in the meaning of Scripture without having an authority to back them up?
Jesus promised the first pope that, "Thou art Peter, and upon this Rock, I will build my Church and the gates of hell shall not prevail against it."
