The spiritual gift of “tongues” in 1 Cor. 12-14 was evidently by itself unintelligible, requiring that someone render what was being said in plain Greek if the Corinthian church was to benefit from it. When discussing the negative effect the utterance would have if left unintelligible, Paul calls a part of the audience the ἰδιῶται (idiotai). Are these believers, unbelievers, Christian catechumens, or what? Jon C. Laansma is the Gerald F.
