s 16:18, we are directed to avoid those who cause divisions.
The Church regards her unity as of such vital importance to her own
life and to the life of each individual soul, she bids us pray in
the Litany, "From all false doctrine, heresy, and Schism, Good Lord,
deliver us." (See UNITY, CHURCH; and also UNDIVIDED CHURCH.)

Scriptures in the Prayer-book.--It has been pointed out, on the
authority of a careful and detailed calculation that of the whole
Prayer-book, three-fifths of it are taken from the Bible and that
two-fifths of all the Church's worship are carried on in the actual
words of Holy Scripture. Again, that one-half of this Divine Service
is Praise; one-fourth, Prayer; and {239} one-fourth, Reading of the
Bible. From these facts, the Episcopal Church has been rightly called
a "Bible Reading Church." We thus learn the great value of the
Prayer-book in setting forth "the things pertaining to the Kingdom
of God." (See LECTIONARY.)

Seasons, The Church.--(See CHRISTIAN YEAR.)

Sedilia.--From the Latin _sedile_, meaning a seat. The name given to
the seats near the Altar, usually placed against the south wall, to
be used by the Clergy during the sermon at the Holy Communion.

See.--Derived from the Latin word _sedes_, meaning a seat. The word
is used to designate the place of a Bishop's Jurisdiction, and his
place of residence, the city where his cathedral is; usually called
the _See City_.

Sentences, The Opening.--Short passages of Holy Scripture read at
the beginning of Daily Morning and Evening Prayer, are so called,
and are intended to strike the keynote of the service to follow.
Originally the Daily Services began with the Lord's Prayer, but in
1552 the Sentences, with the Exhortation, Confession and absolution
were prefixed to Morning Prayer; they were not placed in the Evening
Prayer until 1661. In the last revision of the American Prayer-book
additional Sentences were added and arranged to strike the keynote
of the Church's great Festivals and Fasts, such as Christmas Day,
Good Friday, Easter, etc.

Septuagesima.--The name given to the third Sunday before Lent. The
explanation of this name for this Sunday has been given as follows:
"There being exactly fifty days between the Sunday next {240} before
Lent and Easter Day inclusive, that Sunday is termed _Quinquagesima_,
_i.e._, the fiftieth; and the two Sundays immediately preceding
are called from the next round numbers, _Sexagesima_, _i.e._,
