This is without a doubt the best short book on this topic, as it deals with all the major arguments concerning both the meaning and the mode of baptism.
Some of the propositions set forth in chapter 28 of the Westminster Confession of Faith (Of Baptism) are as follows:
"III. Dipping of the person into the water is not necessary; but baptism is rightly administered by pouring or sprinkling water upon the person.
IV. Not only those that do actually profess faith in and obedience unto Christ, but also the infants of one or both believing parents are to be baptized.
V. Although it be a great sin to contemn or neglect this ordinance, yet grace and salvation are not so inseparably annexed unto it as that no person can be regenerated or saved without it, or that all that are baptized are undoubtedly regenerated.
VI. The efficacy of baptism is not tied to that moment of time wherein it is administered; yet, notwithstanding, by the right use of this ordinance the grace promised is not only offered, but really exhibited and conferred by the Holy Ghost, to such (whether of age or infants) as that grace belongeth unto, according to the counsel of God's own will, in his appointed time.
VII. The sacrament of Baptism is but once to be administered to any person."
In this book Adams defends these positions in an easy to read and incisive manner.
