Notwithstanding on each day, and especially Sundays, the Church celebrates the praises of the Trinity, in her doxologies, hymns, creeds, &c.; yet the wisdom of the Church thought it meet, that such a mystery as this, though part of the meditation of each day, should be the chief subject of one, and this to be the day. For no sooner had our Lord ascended into heaven, and God’s Holy Spirit descended upon the Church; but there ensued the notice of the glorious and incomprehensible Trinity, which before that time was not so clearly known. The Church therefore, having solemnized in an excellent order all the high feasts of our Lord, and after that of the descent of God’s Spirit upon the apostles, thought it a thing most seasonable to conclude these great solemnities with a festival of full, special, and express service to the holy and blessed Trinity.—Bp. Sparrow.

This mystery was not clearly delivered to the Jews, because they, being always surrounded by idolatrous nations, would have easily mistaken it for a doctrine of plurality of Gods; but yet it was not so much hidden in those times, but that any one with a spiritual eye might have discerned some glimmerings of it dispersed through the Old Testament. The first chapter in the Bible seems to set forth three persons in the Godhead; for, besides the “Spirit of God” which “moved upon the face of the waters,” (ver. 2,) we find the great Creator (at the 26th verse) consulting with others about the greatest work of his creation, the making of man, of which we may be assured the Word or Son of God was one, since “all things were made by him, and without him was not anything made that was made.” So that those two verses fully pointing out to us the Father, Son, and Holy Ghost, make this a very proper lesson for the solemnity of the day. The reason of the choice of the other first lesson is as obvious: it records the appearance of the great Jehovah to Abraham, whom the patriarch acknowledges to be the “Judge of all the earth;” and who therefore, by vouchsafing to appear with two others in his company, might design to represent to him the “Trinity of Persons.” But this sacred mystery is nowhere so plainly manifested as in the second lesson for the morning, which at one and the same time relates the baptism of the Son, the voice of the Father, and the descent of the Holy Ghost: which, though they are (as appears from this chapter) three distinct persons in number, yet the second lesson at evening shows they are but one in essence.—Wheatly.

The Epistle and the Gospel are the same that were anciently assigned for the Octave of Pentecost; the Epistle being the vision of St. John (Rev. iv.); and the Gospel, the dialogue of our Lord with Nicodemus; and the mention, which we find therein, of baptism, of the Holy Spirit and the gifts of it, though it might then fit the day as a repetition, as it were, of Pentecost, so is it no less fit for it as a feast of the blessed Trinity. The mission of the Holy Ghost brings with it, as aforesaid, more light and clearness to the doctrine of the Trinity: and when more fit to think of the gifts of the Spirit, than on a solemn day of ordination, as this is one, when men are consecrated to spiritual offices? But, besides this, we have in the Gospel set before us all the three persons of the sacred Trinity, and the same likewise represented in the vision, which the Epistle speaks of, with an hymn of praise, “Holy, holy, holy, Lord God Almighty,” &c.: which expressions, by ancient interpretation, relate to the Holy Trinity, as is above said.—Bp. Sparrow.

In the Roman Church the Sundays between Whitsunday and Advent are reckoned from Pentecost: in our Church, following the old English custom in the unreformed office, we count from Trinity Sunday.

TRISAGION. (See Tersanctus.)

TRUCE OF GOD. In the French, Treve de Dieu: in modern Latin, Trevia, Treuvia, Treuga, or Truga Dei.

In the eleventh century, when the disorders and licences of private wars, between particular lords and families, were a great disturbance to the peace of the kingdom of France, the bishops took upon them to publish injunctions, forbidding acts of violence, within certain times, under canonical pains. These prohibitions were called Truce of God; a phrase frequently to be met with in the councils held about that time.

The first regulation of this kind was in a synod, held in the diocese of Elno in Rousillon, A. D. 1027; where it was enacted, that, throughout that country, no person should attack his enemy, from the hour of nones on Saturday to that of primes on Monday, that Sunday might have its proper celebration: that no person should, at any time, attack a religious or priest walking unarmed; nor any person going to, or returning from, church: that nobody should attack a church, or any house within thirty paces round it: all this under penalty of excommunication.

TRUMPETS, FEAST OF. An annual festival of the Jews, expressly enjoined by the law of Moses, and observed upon the first day of the seventh month, called Tisri, which was the beginning of the civil year.

This festival is expressly called a sabbath, and was a very solemn day, on which no servile work was to be done; only provision made for their meals, which were usually very plentiful at this time. Among other dishes they served up a ram’s head, in memory of that ram which was sacrificed in the room of Isaac; which they fancy was done upon this day.
