After a lengthy exposition of Baptism wherein Tertullian so connects Baptism to faith and obedience he nearly says that Baptism is sufficient to save, presuming the attending graces of faith, repentance, and subequent life long obedience. There is more though, Tertullian enters into a discussion about whether or not people should be baptized at a very young age. This is one for Baptists, because we love to dip them early all while decrying infant baptism. I have put the more relevant portions in bold.
"But they whose office it is[to baptize], know that baptism is not rashly to be administered...
For why is it necessary - if (baptism itself) is not so necessary - that the sponsors likewise should be thrust into danger? Who both themselves, by reason of mortality, may fail to fulfil their promises, and may be disappointed by the development of an evil disposition, in those for whom they stood? The Lord does indeed say, "Forbid them not to come unto me." Let them "come," then, while they are growing up; let them "come" while they are learning, while they are learning whither to come; let them become Christians when they have become able to know Christ. Why does the innocent period of life hasten to the "remission of sins?" More caution will be exercised in worldly matters: so that one who is not trusted with earthly substance is trusted with divine! Let them know how to "ask" for salvation, that you may seem (at least) to have given "to him that asketh." For no less cause must the unwedded also be deferred - in whom the ground of temptation is prepared, alike in such as never were wedded by means of their maturity, and in the widowed by means of their freedom - until they either marry, or else be more fully strengthened for continence. If any understand the weighty import of baptism, they will fear its reception more than its delay: sound faith is secure of salvation." - "On Baptism" ch 18, Tertullian
This is an interesting quote.
