This joy is often denied the believer who is brought up in a Christian community which baptizes infants. Infant baptism creates a false security in the unregenerate who has been baptized. This confusion is prevalent among reformed as well as Lutheran, Anglican and Catholic communities. Efforts to justify infant baptism by reformers have never been fully satisfactory, and have resulted in controversy among reformed theologians. By extending the analogy, Calvin reasoned that since infants were circumcised in the Old Covenant, infants ought to partake of the corresponding ordinance of the New covenant.
Presumption seems to sum up the nature of the problem.
