To be short, I’ll quote John Piper here.
Justin Taylor drew our attention to the fact that Wayne revised section F1 in his new edition of Systematic Theology (pp. 982-983). The section is titled, â€œDo Churches Need to Be Divided Over Baptism?â€
In the first edition, Wayne answered that question no. In the new edition, he does not answer it.
So, I guess you need to do one of two things. Either read the revision and then comment, or just state your views on whether or not churches need to be divided over Baptism. Grudem doesn’t know. Piper says it should not. But what do you say?
