The "Didache" gives extensive instruction in how to distinguish between true and false prophets, as well as commands regarding tithes to prophets in the church. Irenaeus, wrote of 2nd-century believers with the gift of prophecy, while Justin Martyr argued in his "Dialogue with Trypho" that prophets were not found among the Jews in his time, but that the church had prophets. "The Shepherd of Hermas" describes revelation in a vision regarding the proper operation of prophecy in the church. Eusebius mentions that Quadratus and Ammia of Philadelphia were both prominent prophets following the age of the Twelve Apostles. Tertullian, writing of the church meetings of the Montanists (to whom he belonged), described in detail the practice of prophecy in the 2nd-century church.
