"The Library of Congress has received a number of inquiries over the years about a purported letter from Pontius
Pilate to Tiberius Caesar concerning Jesus Christ. The Library does not have such a letter in its collections".
My apologies: I lost track of the source for that quote, which was echoed on a number of sites (forgery).
I have never put to much stock into it.
Isaiah
Who hath believed our report? and to whom is the arm of the LORD revealed? For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him.
St. Augustine suggested that everyone has a different mental image of Jesus. He wrote:
"The physical face of the Lord is pictured with infinite variety by countless imaginations, though whatever it was like He certainly had only one. Nor as regards the faith we have in the Lord Jesus Christ it is in the least relevant to salvation what our imaginations picture Him like...What does matter is that we think of Him as man." (Augustine,
On the Trinity 8.7; E. Hill trans.,
The Trinity, in The Works of St. Augustine, part 1 vol. 5; Brooklyn, N.Y. City Press, 1991, pp. 246-247).
The fourth-century Bishop Cyril of Jerusalem added:
"The Savior comes in various forms to each person according to need. To those who lack joy, He becomes a vine, to those who wish to enter in, He is a door; for those who must offer prayers, He is a mediating high priest. To those in sin, He becomes a sheep, to be sacrificed on their behalf. He becomes "all things to all people" remaining in His own nature what He is. For so remaining, and possessing the true and unchanging dignity of Sonship, as the best of physicians and caring teachers, he adapts himself to our infirmities." Cyril of Jerusalem,
