John MacArthur on D. A. Carson’s theory of tongues in Showing the Spirit:

If that interpretation did not come from one of the most respected academic authors of our day, it would probably gain no traction in any serious forum. But because of that particular writer’s reputation as a distinguished evangelical scholar, many charismatics cling to his idea as if it were a credible defense of their position. It’s not. It is a transparently desperate attempt to defend the indefensible. Implausible theories like that from respected sources only serve to legitimize a movement that, in reality, is built on untenable arguments and exegetical fallacies.
