Acts 21:18

10. But these things are small when compared with what follows. The sacred historian Luke further relates: “And when we were come to Jerusalem, the brethren received us gladly;” and the day following, James, and all the elders who were with him, having expressed their approbation of his gospel, said to Paul: “Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law: and they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs. What is it therefore? The multitude must needs come together: for they will hear that thou art come. …

6. Nevertheless they, who did not believe at first, became afterwards admirable, and illustrious. At least when Paul and they that were of his company were come up to Jerusalem about decrees,they went in straightway unto James. For he was so admired as even to be the first to be entrusted with the bishop’s office. And they say he gave himself up to such great austerity, that even his members became all of them as dead, and that from his continual praying, and his perpetual intercourse with the ground, his forehead became so callous as to be in no better state than a camel’s knees, simply by reason of his striking it so against the earth. …

And the only object of this journey was to visit Peter; thus he pays due respect to the Apostles, and esteems himself not only not their better but not their equal. Which is plain from this journey, for Paul was induced to visit Peter by the same feeling from which many of our brethren sojourn with holy men: or rather by a humbler feeling for they do so for their own benefit, but this blessed man, not for his own instruction or correction, but merely for the sake of beholding and honoring Peter by his presence. …

And as the hands and feet are moved in accordance with the directions of the mind, so likewise, we, having received the grace and strength of the Spirit, and having also the assistance and co-operation of your royal authority, have with one voice declared as piety and proclaimed as truth: that the sacred icons of our Lord Jesus Christ are to be had and retained, inasmuch as he was very man; also those which set forth what is historically narrated in the Gospels; and those which represent our undefiled Lady, the holy Mother of God; and likewise those of the Holy Angels (for they have manifested themselves in human form to those who were counted worthy of the vision of them), or of any of the Saints. …
