Sursum Corda.--The Latin title of that portion of the Communion Office which begins, "Lift up your hearts," which the Latin words mean. This is found almost word for word in every known Liturgy from the earliest times, and without doubt has come down to us from the Apostolic Age. Even at so early a date as A.D. 252 we find St. Cyprian giving an explanation of the meaning and purpose of the _Sursum Corda_ as follows: "It is for this cause that the Priest before worship uses words of introduction and puts the minds of his brethren in preparation by saying, 'Lift up your hearts'; that while the people answer, 'We lift them up unto the Lord,' they may be reminded that there is nothing for them to think of except the Lord." Symbol.--The ancient name for "Creed," which in the Greek language was called _Symbolon_, _i.e._, watchword, by which as the sentinel recognizes a friend, so the Christian soldier is distinguished from the open enemies or false friends of the Religion of Christ. Synod.--The word used in the Eastern Church for what is called in the Western Church a _Council_. It is from a Greek word meaning coming together. (See COUNCIL.) {252} T Table.--(See Lord's Table.) Te Deum.--The Latin title of the hymn beginning "We praise Thee, O God," sung after the First Lesson at Morning Prayer. It is one of the oldest of Christian hymns. The old tradition that it was first sung impromptu and antiphonally by St. Ambrose and St. Augustine at the Baptism of the latter in A.D. 386, is not now accepted, as there is evidence to show that the Te Deum is much older than the time of St. Ambrose. So early as A.D. 252, we find St. Cyprian using almost the same words as occur in the Te Deum. It is now generally believed that this noble canticle in its present form, is a composition of the Fourth or Fifth Century and that it represents a still more ancient hymn. The Te Deum is sung in the Church service every day except during Advent and Lent when the _Benedicite_ is sung instead. Ten Commandments.--(See DECALOGUE.) Temperance.--(See CHURCH TEMPERANCE SOCIETY.) Ter Sanctus.--Meaning _Thrice Holy_. The Latin title of the hymn in the Communion Office beginning "Holy, Holy, Holy." This hymn is of the most ancient origin and forms part of all the oldest Liturgies. In the Liturgies of St. Basil and St. Chrysostom, it is called the "Triumphal Hymn."
