And this is especially needful to be kept in mind by those who, like the most of us, hold fast by the free and spiritual conception of Christianity. That freedom we may turn into a bondage, and that spirituality into a form, if we confound it with the essentials of Christianity, and deny the possibility of the life being developed except in conjunction with it. My text has a double edge. Let us use it against all this Judaising which is going on round about us, and against all the tendency to it in our own hearts. The one edge smites the former, the other edge the latter. Circumcision is nothing, as most of us are forward to proclaim. But, also, remember, when we are tempted to trust in our freedom, and to fancy that in itself it is good, _uncircumcision is nothing_. You are no more a Christian for your rejection of forms than another man is for his holding them. Your negation no more unites you to Christ than does his affirmation. One thing alone does that,--faith which worketh by love, against which sense ever wars, both by tempting some of us to place religion in outward acts and ceremonies, and by tempting others of us to place it in rejecting the forms which our brethren abuse. IV. When an indifferent thing is made into an essential, it ceases to be indifferent, and must be fought against. Paul proclaimed that circumcision and uncircumcision were alike unavailing. A man might be a good Christian either way. They were not unimportant in all respects, but in regard to being united to Christ, it did not matter which side one took. And, in accordance with this noble freedom, he for himself practised Jewish rites; and, when he thought it might conciliate prejudice without betraying principle, had Timothy circumcised. But when it came to be maintained as a principle that Gentiles _must_ be circumcised, the time for conciliation was past. The other side had made further concession impossible. The Apostle had no objection to circumcision. What he objected to was its being forced upon all as a necessary preliminary to entering the Church. And as soon as the opposite party took that ground, then there was nothing for it but to fight against them to the last. They had turned an indifferent thing into an essential, and he could no longer treat it as indifferent.
