Although almost all Evangelical Protestant branches in Ethiopia and Eritrea have one or two theological differences or different approaches in the interpretation of the Bible, all of the four major branches follow the beliefs common to born-again Christians. The four major denominations also exchange pastors ("megabi") and allow the preachers to serve in different churches when invited (full communion). All of the four main churches and others also share and listen to various gospel singers, "mezmur" (gospel music or hymn) producers and choirs.
