For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
All Commentaries on Galatians 5:3 Go To Galatians 5
Epiphanius of Cyprus
AD 403
When he says “bound,” he is no longer speaking of the law as something unworthy but of a heavy burden which can be made lighter. There is one Lord, who is able to make it either heavy or light according to the choice of those who have not refused to accept salvation through his grace through his appearance in the flesh. Panarion, Third Refutation of Marcion.
