Let him, therefore, who is to be taught the truth in regard to piety be instructed before his baptism in the knowledge of the Unbegotten God, in the understanding of His Only-begotten Son, in the assured acknowledgment of the Holy Spirit. Let him learn the order of the several parts of the creation, the series of providential acts, the different workings of God’s laws.
Let him be instructed about why the world was made, and why man was appointed to be a citizen in it; let him also know about his own human nature, of what sort of creature he is; let him be taught how God punished the wicked with water and fire, and glorified the saints in every generation, . . . and how God did not reject mankind, but called them from their error and vanity to acknowledge the truth in various stages of history, leading them from bondage and impiety to liberty and piety, from injustice to justice, from death eternal to everlasting life (Apostolic Constitutions, 7.39.1-4, The Ante-Nicene Fathers, 7:475-76, quoted by D.H. Williams in Tradition, Scripture, and Interpretation [Baker, 2006], p. 82).
These 4th century instructions for how the church should prepare and instruct those seeking baptism in the basics of the Christian faith—that God is Triune, that he alone made the world, etc.—should challenge or at least cause some pause for churches who send people very quickly from profession of faith into baptism.
Has there been such an underestimation of the radical reversal that attends Christian conversion that we suppose new believers need no instruction or mentoring in their new identity prior to their public declaration of faith? Even with all the evidence to the contrary, do we assume that the average person in the post-Christendom West would have a basic understanding of the Christian faith and would not require instruction? Or, have we too often proclaimed a Gospel of easy-believism that bears little resemblance to the New Testament Gospel—a gospel that inverts my allegiances, re-orients my priorities, and re-narrates my life?
Or (less insidiously and maybe more likely), have too many of us embraced an uncertainty, sometimes borne of disinterest, about the relationship between the tenets of Christian orthodoxy and (1) the faith one confesses, (2) the worship and prayers one offers, and (3) the taking up of one’s role in the drama of redemption through vocation and mission?
Too often, God’s triunity and creative action, one’s identity as his creature and one’s place in the world, God’s providential movement throughout history and his eschatological promises—all these are lumped together, called “theology” and are thereby regarded as unnecessary (indeed, even simply un-important) for one to know before baptism.
Or are they?
