The Council of Constantinople- 553 A.D.

(under Pope Vigilius)

…Even though the grace of the holy Spirit was abundant in each of
the apostles, so that none of them required the advice of another in
order to do his work, nevertheless they were loathe to come to a decision
on the issue of the circumcision of gentiles until they had met together
to test their various opinions against the witness of the holy
scriptures.

In this way they unanimously reached the conclusion which they wrote to
the gentiles: It has seemed good to the holy Spirit and to us to lay upon
you no greater burden than these necessary things; that you abstain from
what has been sacrificed to idols and from blood and from what is
strangled and from unchastity. . .

This conciliatory attitude is also to be found in the holy scriptures.
The apostle Paul employed this tactic at the start of his ministry when
he was dealing with those who had been Jews; he circumcised Timothy so
that by this conciliation and concession he might lead them to
perfection. Afterwards, however, he ruled against circumcision, writing
on the subject to the Galatians: Now I Paul say to you that if you
receive circumcision, Christ will be of no advantage to you.
