1689 Baptist Confession 22.3

Chapter 22 — Of Religious Worship and the Sabbath Day

Section 3. Prayer with thanksgiving, being one part of natural worship, is by God required of all men; but that it may be accepted, it is to be made in the name of the Son, by the help of the Spirit, according to his will; with understanding, reverence, humility, fervency, faith, love, and perseverance; and when with others, in a known tongue.
