What were you taught about what Psalm 22 is about?
Being born and raised Jewish from birth to bar mitzvah to 9th grade confirmation, I was never taught anything about the New Testament.
Recently, I have started accompanying my Catholic girlfriend of one year to church -- not because I am Catholic -- but because I like the feeling I get from supporting her and being there to share her experience, even as an outsider.
Perhaps one of these days there will be a reading or homily about the 22nd psalm at her Church.
