WCF 28.5.
Although it be a great sin to condemn or neglect this ordinance, (Luke 7:30, Exod. 4:24–26) yet grace and salvation are not so inseparably annexed unto it, as that no person can be regenerated, or saved, without it: (Rom. 4:11, Acts 10:2, 4, 22, 31, 45, 47) or, that all that are baptized are undoubtedly regenerated. (Acts 8:13, 23)
