In his book
Salvation is from the Jews, Roy Schoeman, a Jewish convert, addresses the silence of Christ before the High Priest by citing the Lemann brothers.
Lemann Brothers - Jewish Converts and Catholic Priests
The Lemann brothers made the touching point that Jesus' silence before the High Priest was motivated by His profound respect for the office of the Jewish Priesthood. Mosaic law forbids compelling a witness to testify against himself. It was because Jesus did not want to put the High Priest in the position of sinning against that law that He refused to answer the High Priest's questions even though beaten for it (Jn 18:19-23). Jesus acquiesced only when the High Priest ordered Him to answer in the name of God.
The Lemann brothers made the touching point that Jesus' silence before the High Priest was motivated by His profound respect for the office of the Jewish Priesthood. That's not what the scripture says: "He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth." (Acts 8:32 which is a quote of...)
"He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth." (Isaiah 53:6)
How could they miss the obvious point of his silence? They are unsaved.
