2. And this certainty of apprehension, sometimes signifieth only the truth of that apprehension, when a man indeed is not deceived, or more usually that clearness of apprehension joined with truth, which fully quieteth the mind and excludeth doubting. 3. We must distinguish of infants as baptized lawfully upon just title, or unlawfully without title. 4. And also of title before God, which maketh a lawful claim and reception at his bar; and title before the church, which maketh only the administration lawful before God, and the reception lawful only _in foro ecclesia_, or _externo_. 5. The word baptism signifieth either the external part only, consisting in the words and outward action, or the internal covenanting of the heart also. 6. And that internal covenant is either sincere, which giveth right to the benefits of God's covenant, or only partial, reserved, and unsound, such as is common to hypocrites. _Conclus._ 1. God hath been pleased to speak so little in Scripture of the case of infants, that modest men will use the words certainly and undoubtedly, about their case, with very great caution. And many great divines have maintained that their very baptism itself, cannot be certainly and undoubtedly proved by the word of God, but by tradition; though I have endeavoured to prove the contrary in a special Treatise on that point. 2. No man can tell what is objectively certain or revealed in God's word, who hath not subjective certainty or knowledge of it. 3. A man's apprehension may be true, when it is but a wavering opinion, with the greatest doubtfulness. Therefore we do not usually by a certain apprehension, mean only a true apprehension, but a clear and quieting one. 4. It is possible to baptize infants unlawfully, or without any right, so that their reception and baptizing shall be a great sin, as is the misapplying of other ordinances. For instance: one in America, where there is neither church to receive them, nor christian parents, nor sponsors, may take up the Indians' children and baptize them against the parents' wills: or if the parents consent to have their children outwardly baptized, and not themselves, as not knowing what baptizing meaneth, or desire it only for outward advantages to their children; or if they offer them to be baptized only in open derision and scorn of Christ; such children have no right to be received. And many other instances nearer may be given. 5. It is possible the person may have no authority at all from Christ who doth baptize them. And Christ's part in reception of the person, and collation and investiture in his benefits, must be done by his commission, or else how can we say that Christ doth it? But open infidels, women, children, mad-men, scorners, may do it that have none of his commission.
