Doctrine 18. We believe that there are two pictorial ordinances in the Lord's churches: Baptism and the Lord's Supper. Scriptural baptism is the immersion of penitent believers in water, administered by the authority of a New Testament church in the name of the Father, Son, and Holy Spirit. The Lord's Supper is a memorial ordinance, restricted to the members of the church observing the ordinance (Matt. 28:19, 20; Acts 8:12, 38; Rom. 6:4; 1 Cor. 5:11-13; 1 Cor. 11:1, 2, 17-20, 26).

Matthew 28:19-20...
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

Acts 8:12,38...
12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women. 38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.

Romans 6:4...
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.

I Corinthians 5:11-13...
11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. 12 For what have I to do to judge them also that are without? do not ye judge them that are within? 13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.

I Corinthians 11:1-2, 17-20, 26...
1 Be ye followers of me, even as I also am of Christ. 2 Now I praise you, brethren, that ye remember me in all things, and keep the ordinances, as I delivered them to you. 17 Now in this that I declare unto you I praise you not, that ye come together not for the better, but for the worse. 18 For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it. 19 For there must be also heresies among you, that they which are approved may be made manifest among you. 20 When ye come together therefore into one place, this is not to eat the Lord's supper. 26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
