[The Holy Roman Church] firmly... asserts that after the promulgation of the gospel they cannot be observed without loss of eternal salvation. Therefore it denounces all who after that time observe circumcision, the [Jewish] sabbath and other legal prescriptions as strangers to the faith of Christ and unable to share in eternal salvation, unless they recoil at some time from these errors. Therefore it strictly orders all who glory in the name of Christian, not to practise circumcision either before or after baptism, since whether or not they place their hope in it, it cannot possibly be observed without loss of eternal salvation.
