These students were in their teens and twenties. The appeal for an officially recognized Pentecostal organization was rejected by the royal government. This was only the beginning of political repression, which accelerated in the 1970s. On one 1972 Sunday alone, 250 worshipers were arrested. In 1979, the Derg government shut down the Addis Ababa FBGC church. During the Derg period, Pentecostalism was targeted with the goal of stopping its practice by closing churches and beating and imprisoning practitioners. This was done to produce fear in believers and scare them from practicing Pentecostalism. Converted believers decided to return to their traditional culture. In a survey of non-orthodox Christians, 16 percent classified as Pentecostals during the Derg reign. All Protestant, Evangelical, Pentecostal, and born-again Christians were labeled as "Pente". This term was first used in a derogatory and mocking tone during the Derg rein. The term was first associated with the group after an attack on hundreds of Pentecostal youth in Debre Zeit in 1976. During the time when Pentecostals had to practice in closed areas, radio was one of the few methods they could rely on to spread their messages. In 1967 despite previous legislation, the registration of the Mulu Wengel Church was denied. People from outside the Pentecostal movement were alarmed by the "emotional stirring" brought about by the Gifts of the Holy Spirit. In 1979 Gudina Tumsa, Secretary General of the Mekane Yesus Church was executed, further forcing Pente groups to move their activities underground. Despite the desire for unity among Pentecostal leaders, many churches were small in numbers and divided from other Pentecostal churches. Because the Ethiopian Orthodox Church has evolved throughout Ethiopian History, it has received certain privileges from the government. During the 1960s, the Ethiopian Orthodox Church was the only Christian denomination accepted by the government. This caused the emergence of Open and Closed areas where Orthodox Churches could practice freely, while Pentecostal churches and other denominations were forced to practice in private and keep a low profile. This governmental support of the Orthodox Church has led Pentecostals to structure their movement around national unity and to use to slogan "the Gospel for Ethiopia by Ethiopians". To further demonstrate national unity, Pentecostal churches rely on languages to reach more people. This is a practice taken from the Orthodox church, which uses Ge’ez. In Wolaita, people did not want to take on the Orthodox Christianity that was imposed by their conquerors, and many converted to Protestant Christianity.
