No. Let’s examine what the Scriptures teach on this issue:

First, it is quite clear from such passages as Acts 15 and Romans 4 that no external act is necessary for salvation. Salvation is by divine grace through faith alone (Romans 3:22, 24, 25, 26, 28, 30; 4:5; Galatians 2:16; Ephesians 2:8-9; Philippians 3:9, etc.).

If water baptism were necessary for salvation, we would expect to find it stressed whenever the gospel is presented in Scripture. That is not the case, however. Peter mentioned baptism in his sermon on the day of Pentecost (Acts 2:38). However, in his sermon from Solomon’s portico in the Temple (Acts 3:12-26), Peter makes no reference to baptism, but links forgiveness of sin to repentance (3:19). If baptism is necessary for the forgiveness of sin, why didn’t Peter say so in Acts 3?

Paul never made water baptism any part of his gospel presentations. In 1 Corinthians 15:1-4, Paul gives a concise summary of the gospel message he preached. There is no mention of baptism. In 1 Corinthians 1:17, Paul states that “Christ did not send me to baptize, but to preach the gospel,” thus clearly differentiating the gospel from baptism.

Those passages are difficult to understand if water baptism is necessary for salvation. If baptism were part of the gospel itself, necessary for salvation, what good would it have done Paul to preach the gospel, but not baptize? No one would have been saved. Paul clearly understood water baptism to be separate from the gospel, and hence in no way efficacious for salvation.

Perhaps the most convincing refutation of the view that baptism is necessary for salvation are those who were saved apart from baptism. The penitent woman (Luke 7:37-50), the paralytic man (Matthew 9:2), the publican (Luke 18:13-14), and the thief on the cross (Luke 23:39-43) all experienced forgiveness of sins apart from baptism. For that matter, we have no record of the apostles’ being baptized, yet Jesus pronounced them clean of their sins (John 15:3—note that the Word of God, not baptism, is what cleansed them).

The Bible also gives us an example of people who were saved before being baptized. In Acts 10:44-48, Cornelius and those with him were converted through Peter’s message. That they were saved before being baptized is evident from their reception of the Holy Spirit (v. 44) and the gifts of the Spirit (v. 46) before their baptism. Indeed, it is the fact that they had received the Holy Spirit (and hence were saved) that led Peter to baptize them (cf. v. 47).

One of the basic principles of biblical interpretation is the analogia scriptura, the analogy of Scripture—we must compare Scripture with Scripture in order to understand its full and proper sense. Since the Bible doesn’t contradict itself, any interpretation of a specific passage that contradicts the general teaching of the Bible is to be rejected.

Since the general teaching of the Bible is, as we have seen, that baptism and other forms of ritual are not necessary for salvation, no individual passage could teach otherwise. Thus we must look for interpretations of those passages that will be in harmony with the general teaching of Scripture.

With that in mind, let’s look briefly at some passages that appear to teach that baptism is required for salvation.

In Acts 2:38, Peter appears to link forgiveness of sins to baptism. But there are several plausible interpretations of this verse that do not connect forgiveness of sin with baptism. It is possible to translate the Greek preposition eis—”because of,” or “on the basis of,” instead of “for.” It is used in that sense in Matthew 3:11; 12:41; and Luke 11:32.

It is also possible to take the clause “and let each of you be baptized in the name of Jesus Christ” as parenthetical. Support for that interpretation comes from that fact that “repent” and “your” are plural, while “be baptized” is singular, thus setting it off from the rest of the sentence. If that interpretation is correct, the verse would read “Repent (and let each of you be baptized in the name of Jesus Christ) for the forgiveness of your sins.” Forgiveness is thus connected with repentance, not baptism, in keeping with the consistent teaching of the New Testament (cf. Luke 24:47; John 3:18; Acts 5:31; 10:43; 13:38; 26:18; Ephesians 5:26).
