Early Jewish believers struggled
to reconcile their new faith in Christ with the old traditions. They
had been convinced by the Holy Spirit that Jesus was the Messiah but
had a hard time believing He was the Son of God. They were shocked
when Paul told them that the Levitical priesthood had come to an end
and had been replaced by an eternal priesthood with Jesus as the
high priest. This was distressing because they had faithfully
attended synagogue and participated in the sacrifices and
celebrations at the temple in Jerusalem; life as they knew it had
been radically changed.
The people of Israel received the law under the Levitical
priesthood, and if the law were perfect, what need was there for a
new priesthood? But if the law changed, it would also necessitate a
change in the priesthood as well. This is what happened with the
Second Covenant where God reconciled mankind to Himself by Jesus'
death on the cross.
