 Nontrinitarians, on the other hand, will generally state that the traditional doctrine of the Trinity did not exist until centuries after the end of the New Testament period.Some Trinitarians agree with this, seeing a development over time towards a true understanding of the Trinity.Trinitarians sometimes refer to Christian belief about God before the traditional statements on the Trinity as unsophisticated, 'naive', or 'incipient Trinitarianism', and that early Christians were 'proto-Trinitarian, partially Trinitarian', etc.
