Pastor Mark mentioned on Sunday that the week prior to Jesus' crucifixion is called "Passion Week" but "passion" in this context doesn't mean how it is popularly understood.  "Passion" in this context refers to Jesus "passive" reception of all of His suffering.  It refers to Jesus refusal to resist all of the injustices perpetrated against Him.
Scriptures: Matthew 21:1-11
Matthew 26:14-Matthew 27:66
