In recent months I’ve written a few posts on paedobaptism (infant baptism). As students of theology know, theology is never done in a vacuum. For example, Alexander Campbell, one of the leaders of the 18th century Restoration Movement (Disciples of Christ, Christian Churches, Churches of Christ), came to the US from Scotland as a Presbyterian. Eventually he would gave up his Presbyterianism, after a few doctrinal disputes.
Alexander Campbell would go on to receive baptism at the hand of a Baptist minister. But eventually Campbell would be faced with the question of whether to baptized his infant children or not. You see, his Presbyterianism came into play here. After studying the matter at length, Campbell decided that he did not need to baptize his infant, concluding that they were not proper subjects, not part of the new covenant people of God.
Last weekend, I had a dialogue with two Presbyterian colleagues of mine regarding Jeremiah 31:31-34 and the question of who are the new covenant people of God. With the help of Tom Schreiner of Southern Seminary, I shared with my colleagues that based on the language of Jeremiah 31:33, 34, which is regenerational in nature (compare Ezekiel 36:25-27), the new covenant people of God are the regenerate, not the unregenerate–therefore excluding believers infant children.
But alas, my Presbyterian brothers thought that Schreiner and myself were over-stretching here, making a logical leap that is not warranted by the text of Jeremiah 31:31-34.
