In proportion as the members of the assembly did not understand the teaching, they needed an external confirmation of their incomplete understanding. And so, to solve the question, the very putting of which shows the failure to comprehend the teaching, the strange words, "It has seemed good to the Holy Ghost, and to us," which were in an external manner to confirm the justice of certain establishments, and which have caused so much evil, were, as described in the Book of Acts, for the first time pronounced at this meeting, that is, it was asserted that the justice of what they decreed was testified to by the miraculous participation of the Holy Ghost, that is, of God, in this solution. But the assertion that the Holy Ghost, that is, God, spoke through the apostles, had again to be proved. And for this it was necessary to assert that on the day of Pentecost the Holy Ghost came down in the shape of tongues of fire on those who asserted this. (In the description the descent of the Holy Ghost precedes the assembly, but the Acts were written down much later than either.) But the descent of the Holy Ghost had to be confirmed for those who had not seen the tongues of fire (though it is incomprehensible why a tongue of fire burning above a man's head should prove that what a man says is an indisputable truth), and there were needed new miracles, cures, resurrections, putting to death, and all those offensive miracles, with which the Acts are filled, and which not only can never convince a man of the truth of the Christian teaching, but can only repel him from it. The consequence of such a method of confirmation was this, that the more these confirmations of the truth by means of stories of miracles heaped up upon one another, the more did the teaching itself depart from its original meaning, and the less comprehensible did it become.
