A look at the problem tongues of Corinth being an internal linguistic struggle between Doric, Aeolic, and Attic Greeks.
This is part 2 of an 7 part series on the mystery tongues of Corinth. Part 1, The Role of Hebrew in the Jewish Aramaic World, covered how Hebrew became the language of religion and worship in Aramaic Judaism. The precedence about Hebrew established here transferred over to Jews living in a Greek world.
When you add that the ancient synagogue liturgy of Hebrew as the language of instruction was adopted in the Corinthian assembly, then we are getting close to finding a good answer to the question of Corinthian tongues.
This conclusion is greatly strengthened by a fourth-century church father by the name of Epiphanius. He did not stop at explaining the tongues of Corinth as being a problem of Hebrew instruction. He further commented it was a linguistic conflict between Doric, Aeolic, and Attic Greeks.
