'Ordinances' in the Bible

Believers, I beg of you, become as I am [free from the bondage of Jewish ritualism and ordinances], for I have become as you are [a Gentile]. You did me no wrong [when I first came to you; do not do it now].

Once more I solemnly affirm to every man who receives circumcision [as a supposed requirement of salvation], that he is under obligation and required to keep the whole Law.
