I. An account of those who are excluded from this privilege, _viz._ such as are out of the visible church, and so strangers from the covenant of promise. The visible church is here considered in the most large and less proper acceptation of the word, as denoting all who profess the true religion; and in this respect is opposed to the Jews and heathen, and those who, though they live in a Christian nation, are grossly ignorant of the gospel, and act as though they thought that it did not belong to them, not seeing themselves obliged to make any profession thereof: These may be ranked among infidels, as much as the heathen themselves; and, according to this sense of the word, are not members of the visible church; and, consequently, while they remain so, are not to be admitted to baptism. This is agreeable to the sentiments and practice of most of the reformed churches; and it cannot but be reckoned highly reasonable, by all who consider baptism as an ordinance in which a public profession is made of the person’s being devoted to God the Father, Son, and Holy Ghost; and, if he be considered as adult (and of such we are now speaking) there is a signification, and thereby a profession made, that he gives up himself to God; and, if the ordinance be rightly applied, there must be an harmony between the inward design of the person dedicating, and the true intent and meaning of the external sign thereof; which, by divine appointment, is a visible declaration of his adhering by faith, to the Father, Son, and Holy Ghost, and embracing that salvation which takes its rise from them. This therefore must be done by faith; or else the ordinance is engaged in after an hypocritical manner; which will tend to God’s dishonour, and the prejudice rather than the advantage of him, to whom it is administered. II. We are now to consider the necessity of their making a profession of their faith in Christ, and obedience to him, who being adult, are admitted to baptism. It was supposed, under the last head, that if there be not an harmony between the internal frame of spirit, in the person baptized, and the intent of the external sign thereof, the ordinance is not rightly applied to him, inasmuch as he pretends to dedicate himself to God; but, in reality does not do this by faith: And now it may be farther considered, that it is necessary that he should make it appear, that he is a believer, by a profession of his faith; otherwise, he that administers the ordinance, together with the assembly, who are present at the same time, cannot conclude that they are performing a service that is acceptable to God; therefore, for their sakes, as well as his own, the person to be baptized, ought to make a profession of his subjection to Christ, as what is signified in this ordinance.
