1 Peter 3:18-22

For Christ also died once and for all for our sins, the just for the unjust, that he might bring us to God. He was put to death in the flesh, but he was raised to life in the Spirit, in which also he went and preached to the spirits who are in prison, the spirits who were once upon a time disobedient in the time when the patience of God waited in the days of Noah, while the ark was being built, in which some few--that is, eight souls--were brought in safety through the water. And water now saves you, who were symbolically represented in Noah and his company, I mean the water of baptism; and baptism is not merely the removal of dirt from the body, but the pledge to God of a good conscience, through the resurrection of Jesus Christ, who is at the right hand of God, because he went to heaven, after angels and authorities and powers had been made subject to him.

Peter has been speaking about the wicked men who were disobedient and corrupt in the days of Noah; they were ultimately destroyed. But in the destruction by the flood eight people--Noah and his wife, his sons Shem, Ham and Japheth, and their wives--were brought to safety in the ark. Immediately the idea of being brought to safety through the water turns Peter's thoughts to Christian baptism, which is also a bringing to safety through the water. What Peter literally says is that baptism is an antitype of Noah and his people in the ark.

This word introduces us to a special way of looking at the Old Testament. There are two closely connected words. There is tupos (G5179), type, which means a seal, and there is antitupos (G499), antitype, which means the impression of the seal. Clearly, between the seal and its impression there is the closest possible correspondence. So there are people and events and customs in the Old Testament which are types, and which find their antitypes in the New Testament. The Old Testament event or person is like the seal; the New Testament event or person is like the impression; the two answer to each other. We might put it that the Old Testament event symbolically represents and foreshadows the New Testament event. The science of finding types and antitypes in the Old and the New Testaments is very highly developed. But to take very simple and obvious examples, the Passover Lamb and the scapegoat, who bore the sins of the people, are types of Jesus; and the work of the High Priest in making sacrifice for the sins of the people is a type of his saving work. Here Peter sees the bringing safely through the waters of Noah and his family as a type of baptism.

In this passage Peter has three great things to say about baptism. It must be remembered that at this stage of the Church's history we are still dealing with adult baptism, the baptism of people who had come straight from heathenism into Christianity and who were taking upon themselves a new way of life.

(i) Baptism is not merely a physical cleansing; it is a spiritual cleansing of the whole heart and soul and life. Its effect must be on a man's very soul and on his whole life.

(ii) Peter calls baptism the pledge of a good conscience to God (1 Peter 3:21). The word Peter uses for pledge is eperotema (G1906). In every business contract there was a definite question and answer which made the contract binding. The question was: "Do you accept the terms of this contract, and bind yourself to observe them?" And the answer, before witnesses was: "Yes." Without that question and answer the contract was not valid. The technical word for that question and answer clause is eperotema (G1906) in Greek, stipulatio in Latin.

Peter is, in effect, saying that in baptism God said to the man coming direct from heathenism: "Do you accept the terms of my service? Do you accept its privileges and promises, and do you undertake its responsibilities and its demands?" And in the act of being baptized the man answered: "Yes."

Some use the word sacrament. Sacrament is derived from the Latin sacramentum, which means a soldier's oath of loyalty on entering the army. Here we have basically the same picture. We cannot very well apply this question and answer in infant baptism, unless it be to the parents; but, as we have said, baptism in the very early church was of adult men and women coming spontaneously from heathenism into the Church. The modern parallel is entering upon full membership of the Church. When we enter upon Church membership, God asks us: "Do you accept the conditions of my service, with all privileges and all its responsibilities, with all its promises and all its demands?" and we answer; "Yes." It would be well if all were clearly to understand what they are doing when they take upon themselves membership of the Church.

(iii) The whole idea and effectiveness of baptism is dependent on the resurrection of Jesus Christ. It is the grace of the Risen Lord which cleanses us; it is to the Risen, Living Lord that we pledge ourselves; it is to the Risen, Living Lord that we look for strength to keep the pledge that we have given. Once again, where infant baptism is the practice, we must take these great conceptions and apply them to the time when we enter upon full membership of the Church.
