Yet we are not to steal from God's Word to Israel.
Nor are we to add offices to the NT Church that the Apostles did not.
Nor are we to incorporate syncretic paganism into the Church.
Not sure where you are going with this. The Bible, both new and old testament, belong to the christian and the church. Is your argument something about cultural appropriation?
Nor are we to add offices to the NT Church that the Apostles did not.

Nor are we to incorporate syncretic paganism into the Church.

God’s word which is also given to the Christian faith and to the belivers.
