Typical anti-Mormon tactic—change the subject.
Let’s get back to the topic of baptism. Let’s see a statement from each one of those denominations on whether baptism is a requirement for salvation, who can perform it, how it is to be performed, and who has authority to perform it.
You will find legitimate differences in the way each one of those denominations interprets the Bible vis-a-vis the doctrine of baptism. That was the point I was making. A doctrinal exclusion of Mormonism must be equally applied across the spectrum of Christian practice. If Catholics, Baptists, Lutherans, Presbyterians, and Methodists all have differing doctrines and they all use the Bible, something must be amiss with them. They can’t all correct.
