Ultra-dispensationalism is a form of Dispensationalism. It is called "Ultradispensationalism" because many Denominations consider it to be unorthodox. Ultradispenationalism teaches that the Church began when the events of Acts 28 occurred. Ultradispensationalists believe that after Pentecost, the Body of Christ used to be exclusive to Jews. According to Ultradispensationalism, that ended when a new Dispensation known as "The dispensation of Grace" began when the events of Acts 28 occurred.
