“The problem with all of this, of course, is that it tends to leave us with little that is normative for two broad areas of concern — Christian experience and Christian practice. There is no express teaching on such matters as the mode of baptism, the age of those who are to be baptized, which charismatic phenomenon is to be in evidence when one receives the Spirit, or the frequency of the Lord’s Supper, to cite but a few examples. Yet these are precisely the areas where there is so much division among Christians. Invariably, in such cases people argue that this is what the earliest believers did, whether such practices are merely described in the narratives of Acts or found by implication from what is said in the Epistles. Scripture simply does not expressly command that baptism must be by immersion, or that infants are to be baptized, or that all genuine conversions must be as dramatic as Paul’s, or that Christians are to be baptized in the Spirit evidenced by tongues as a second work of grace, or that the Lord’s Supper is to be celebrated every Sunday. What do we do, then, with something like baptism by immersion? What does Scripture say? In this case it can be argued from the meaning of the word itself, from the one description of baptism in Acts of going “down into the water” and coming “up out of the water” (8:38 – 39), and from Paul’s analogy of baptism as death, burial, and resurrection (Rom 6:1 – 3) that immersion was the presupposition of baptism in the early church. It was nowhere commanded precisely because it was presupposed. On the other hand, it can be pointed out that without a baptismal tank in the local church in Samaria (!), the people who were baptized there would have had great difficulty being immersed. Geographically, there simply is no known supply of water there to have made immersion a viable option. Did they pour water over them, as an early church manual, the Didache (ca. AD 100), suggests should be done where there is not enough cold, running water or tepid, still water for immersion? We simply do not know, of course. The Didache makes it abundantly clear that immersion was the norm, but it also makes it clear that the act itself is far more important than the mode. Even though the Didache is not a biblical document, it is a very early, orthodox Christian document, and it may help us by showing how the early church made pragmatic adjustments in this area where Scripture is not explicit. The normal (regular) practice served as the norm. But because it was only normal, it did not become normative. We would probably do well to follow this lead and not confuse normalcy with normativeness in the sense that all Christians must do a given thing or else they are disobedient to God’s Word.”

“We are also priests, because Peter calls us “a royal priesthood” (1 Peter 2:9). He invites us to be built into a spiritual temple and “to be a holy priesthood” as well as “to offer spiritual sacrifices acceptable to God through Jesus Christ” (1 Peter 2:5). The author of Hebrews also views us as priests who are able to enter into the holy of holies (Heb. 10:19, 22) and able to “continually offer up a sacrifice of praise to God, that is, the fruit of lips that acknowledge his name” (Heb. 13:15). He also tells us that our good works are sacrifices pleasing to God: “Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God” (Heb. 13:16). Paul also has a priestly role in mind for us when he writes, “I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship” (Rom. 12:1).”
