This is a great mystery to us, which, however, we are not called upon to understand, but only to believe on the plain statement of Scripture.
The Father is God, John vi, 27; Gal. i. 1; 1 Thess. i. 1, &c.
The Son is God, John i. 1; xx. 28; Rom. ix. 5, &c.
The Holy Ghost is God. This, however, has to be proved by implication and analogy, as with Luke i. 35 compare Matt. i. 18; Acts v. 3, 4, with John iii. 6 compare 1 John v. 4; with 1 Cor. iii. 16 compare vi. 19, &c.
The unity of the Godhead is declared in many such passages as
Deut. vi. 4; Gal. iii. 20; John x. 30, &c.
The Son of God, our Lord Jesus Christ, "took man's nature in the womb of the blessed Virgin, of her substance; so that the two whole and perfect natures, that is to say the Godhead and Manhood, were joined together in one Person, never to be divided, whereof is one Christ very God and very Man." (Art. ii. and Luke i.)
TRINITY SUNDAY. This is a festival of Western origin, and of comparatively recent date; the earliest formal notice of the festival is in England, under Becket, in 1162; though the collect dates from the 5th century.
TRIUMPHANT, The CHURCH. Those who have departed this life in God's faith and fear; the Church in Heaven. The Church on earth is called the Church Militant.
TUNICLE, see Vestments.
TYPE. An impression, image, or representation of some model which is termed the anti-type; thus the brazen serpent and the paschal lamb were types, of which our Lord was the anti-type.
