At Trinity Western Christians

From the 14th century celebration of the Trinity (Trinity Sunday) in the Catholic church became known as the first Sunday after the Pentecost.

Trinity in Christian ideas — God, whose essence is one, but His being is a personal attitude of the three persons : the Father — without beginning primordial, son — an absolute sense, incarnate in Jesus Christ, and the Holy Spirit — the life-giving Principle.

According to Catholic doctrine, the third subsistence comes from the First and Second (by Orthodox — from the first ).
