Belgic Confession Of Faith

Article XXXIV
Holy Baptism (Part 3)

Leader: The ministers, therefore, on their part administer the sacrament and that which is visible, but our Lord gives that which is signified by the sacrament, namely, the gifts and invisible grace; washing, cleansing, and purging our souls of all filth and unrighteousness; renewing our hearts and filling them with all comfort; giving unto us a true assurance of His fatherly goodness; putting on us the new man, and putting off the old man with all his deeds.

People: We believe, therefore, that every man who is earnestly studious of obtaining life eternal ought to be baptized but once with this only baptism, without ever repeating the same, since we cannot be born twice. Neither does this baptism avail us only at the time when the water is poured upon us and received by us, but also through the whole course of our life.
