There were, as we all know, in the Church of those days powerful sections of professed believers, who contested Paul's apostleship, questioned his teaching, and wholly disliked the effects of his work. Perhaps by this time the strain of that conflict had become a little less severe, but it had not wholly passed away. We call these persons the Judaisers. They were men who looked to Jesus Christ as the Messiah, who owned the authority of His teaching, and claimed interest in His promises. But they insisted on linking Christianity to Jewish forms, and rules, and conditions of law-keeping, which were on various grounds dear and sacred to them. They apprehended feebly the spirituality and Divineness of Christ's religion; and what they did apprehend they wished to enslave, for themselves and others, in a carnal system of rules and ritual that tended to stifle and to bury the truth. With this there went a feeling towards Paul of wrath fear, and antipathy. Such men there were in Rome. Possibly there might even be a Christian congregation in the city in which this type prevailed. At any rate, they were found there. Before Paul's coming no very remarkable nor very successful efforts to spread abroad the gospel in that great community had been going on. But Paul's arrival made men solicitous and watchful. And when it was seen that his presence and the enthusiasm that gathered round him were beginning to give impulse and effect to the speaking of the word, then this party too bestirred itself. It would not--could not--oppose the carrying of the message of Christ to men. But it could try to be first in the field; it could become active, energetic, dexterous, in laying hold of inquiring and susceptible persons, before the other side could do so; it could subject Paul to the mortification, _the deserved mortification_, of failure or defeat, so far as these would be implied in his seeing the converts going to the side which was not his side. Evangelistic zeal awoke on these terms, and bestirred itself. And sheaves that in other circumstances might have lain untended long enough, were gathered now.
