The injunction implies that there are cases in which the father is a good Christian, but he has not succeeded in making his children good Christians. Either they have not become believers at all; or, although nominal Christians, they do not conduct themselves as such. They are profligate, riotous, and disobedient. This implies that the children are old enough to think for themselves and reject the Gospel in spite of their parent's conversion; or that they are old enough to rebel against its authority. And one does not use such strong words as "profligacy" or "riotous living" of quite young children. The prodigal son, of whom the same expression is used, was no mere child. Cases of this kind, therefore, in which the father had been converted to Christianity, but had been unable to make the influences of Christianity tell upon his own children, were common enough to make it worth St. Paul's while to give injunctions about them. And this implies a condition of things in which Christianity was no newly planted religion. The injunctions are intelligible enough. Such fathers are not to be selected by Titus as elders. A man who has so conspicuously failed in bringing his own household into harmony with the Gospel, is not the man to be promoted to rule the household of the Church. Even if his failure is his misfortune rather than his fault, the condition of his own family cannot fail to be a grave impediment to his usefulness as an overseer of the congregation.[72] Thirdly, there is the fact that heresies already exist among the Cretan Christians. Titus, like Timothy, has to contend with teaching of a seriously erroneous kind. From this also we infer that the faith has long since been introduced into the island. The misbeliefs of the newly converted would be spoken of in far gentler terms. They are errors of ignorance, which will disappear as fuller instruction in the truth is received. They are not erroneous doctrines held and propagated in opposition to the truth. These latter require time for their development. From all these considerations, therefore, we conclude that St. Paul is writing to Titus as his delegate in a country in which the Gospel is no new thing. We are not to suppose that the Apostle left Titus in charge of Christians who had been converted a very short time before to the faith.
The incompleteness of the Apostle's own work in the island is spoken of in plain terms. Even in Churches in which he was able to remain for two or three years, he was obliged to leave very much unfinished; and we need not be surprised that such was the case in Crete, where he can hardly have stayed so long. It was this incompleteness in all his work, a defect quite unavoidable in work of such magnitude, that weighed so heavily upon the Apostle's mind. It was "that which pressed upon him daily,--anxiety for all the Churches." There was so much that had never been done at all; so much that required to be secured and established; so much that already needed correction. And while he was attending to the wants of one Church, another not less important, not less dear to him, was equally in need of his help and guidance. And here was the comfort of having such disciples as, Timothy and Titus, who, like true friends, could be indeed a "second self" to him. They could be carrying on his work in places where he himself could not be. And thus there was no small consolation for the sorrow of parting from them and the loss of their helpful presence. They could be still more helpful elsewhere. "For this cause left I thee in Crete, that thou shouldest set in order the things that were wanting."
There were many things that were wanting in Crete; but one of the chief things which pressed upon the Apostle's mind was the lack of a properly organized ministry, without which everything must soon fall into confusion and decay. Hence, as soon as he has concluded his salutation, the fulness and solemnity of which is one of the many evidences of the genuineness of the letter, he at once repeats to Titus the charge which he had previously given to him by word of mouth respecting this pressing need. A due supply of elders or overseers is of the first importance for "setting in order" those things which at present are in so unsatisfactory a state.
