'Ceremonies' in the Bible

For we are the true circumcision--we who render to God a spiritual worship and make our boast in Christ Jesus and have no confidence in outward ceremonies:

although I myself might have some excuse for confidence in outward ceremonies. If any one else claims a right to trust in them, far more may I:

For their efficacy depends only on meats and drinks and various washings, ceremonies pertaining to the body and imposed until a time of reformation.
