Ordinance: the word stresses "what God has done" rather than: Sacrament - "a promise of what I will do. "
True ordinances were instituted in the Gospels, practiced in the Acts, and taught in the Epistles.
The Greek word "baptizo " means to dip or immerse. The Greek language has a word meaning to sprinkle (rantizo) which is used six times in the N. T. but never to signify baptism.
In Scripture, baptism always means that a new relationship has been established.
There are several types of baptism:
Salvation - See Acts 2:41; 8:12; 8:36-39, etc.
All persons baptized in the Acts or Epistles were first born again.
Matt. 28:1 8- 20 shows that a relationship with God has been established.
Rom. 6:1-4 explains that baptism is an identification with death, i. e. , the death of Christ.
NOTE: The mode of believer's baptism is immersion; not only because the word meaning demands it, and because this was the way it was practiced in the Scripture (cf. John 3:23; Acts 8:38- 39) but further, only by going under water and coming up out is a fitting symbol given of our identification with Christ in His death, burial, and resurrection.
baptism as joining one to a local church (but see Acts 2:41, 47).
baptism as a saving or meritorious act (rather it is the answer of a good conscience toward God, I Pet. 3:21).
