Christians are known as continuationists. These charismata may include prophecy, tongues, miraculous healing ability, and discernment (Matthew 12:32 KJV "Whosoever speaketh a word against the Son of Man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come."). Cessationists believe that these gifts were given only in New Testament times and that they ceased after the last apostle died. The last prophet of the Old Covenant before the arrival of Jesus is John the Baptist. New Testament passages that explicitly discuss prophets existing after the death and resurrection of Christ include Revelation 11:10, Matthew 10:40–41 and 23:34, John 13:20 and 15:20 and Acts 11:25–30, 13:1 and 15:32. 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. A number of later Christian saints were claimed to have powers of prophecy, such as Columba of Iona (521–597), Saint Malachy (1094–1148) or Padre Pio (1887–1968). Marian apparitions like those at Fatima in 1917 or at Kibeho in Rwanda in the 1980s often included prophetic predictions regarding the future of the world as well as of the local areas they occurred in. Prophetic movements in particular can be traced throughout the Christian Church's history, expressing themselves in (for example) Montanism, Novatianism, Donatism, Franciscanism, Anabaptism, Camisard enthusiasm, Puritanism, Quakerism, Quietism, Lutheranism and Radical Pietism. Modern Pentecostals and Charismatics, members of movements which together comprised approximately 584 million people , believe in the contemporary function of the gift of prophecy, and some in these movements, especially those within the Apostolic-Prophetic Movement, allow for idea that God may continue to gift the church with some individuals who are prophets. Some Christian sects recognize the existence of
