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
John Chrysostom
AD 407
The provisions of the law imply one another. I mean something like this. Attached to circumcision are sacrifice and the observance of days. The sacrifice again entails the observance of a day and place, the place entailing many types of purification. The purifications set up a further string of varied observances. For it is not legitimate for the impure to sacrifice, to intrude upon the holy shrines or to do any such things. Therefore through this one commandment the law drags along many others. Now if you have been circumcised but not on the eighth day; or on the eighth day but without a sacrifice; or with sacrifice but not in the appointed place; or in the appointed place but not under the prescribed forms; or under the prescribed forms but not in a pure state; or in a pure state but purified by inappropriate rites— all these things are wasted. For this reason “he is bound to keep the whole.” “Do not keep part but the whole,” Paul says, “but if it is not of the Lord, do not keep even part.”
