Modalism - In Christianity, Sabellianism (also known
as modalism) is the second-century belief that the three persons
of the Trinity are merely different modes or aspects of God,
rather than three distinct persons. It is attributed to Sabellius,
who taught a form of this doctrine in Rome in the second century.
The view that the three members of the Trinity are different
modes of God's activity rather than separate Persons.
