"When did Messiah Yehoshua officially identify Himself with Israel, so as to pay for their sins?"

 
Hello, John and Doves, 
To answer this question, we consider the 7 sayings on the Cross, and one of His comments stands out immediately.
Let us consider Psalm 22 from a purely Jewish [non-messianic] point of view.

Even here, we see room for Jesus to have represented everyone who has found himself/herself in a pickle, or even a relish chopper!
The Church has been welcomed into the fold called Israel.  Since all salvation must conform to Torah [or it is invalid], we see that this is so. And yet, God's chosen, the sons of Abraham, Isaac, and Jacob [The Bride of Christ is associated only with Abraham.] will yet be redeemed, for the Blood is timeless.
