The Athanasian Creed is a Christian statement of belief focused on the Trinitarian doctrine and Christology. It is the first creed in which the equality of the three persons of the Trinity is explicitly stated. Swedenborg spoke in virtually all his works against what he regarded as the incomprehensible Trinity of Persons concept. He said that people of other religions opposed Christianity because of its doctrine of a Trinity of Persons. He considered the separation of the Trinity into three separate Persons to have originated with the First Council of Nicaea and the Athanasian Creed. According to Swedenborg the Athanasian Creed is true, however, if by a trinity is understood to mean a trinity in one person and that person is in the Lord God Jesus Christ.
