Baptized children are members of the body of Christ.
On what biblical basis should baptized children be admitted to the Lord's Supper? Jeffrey J. Meyers' book proposes a number of questions like this one while providing answers that show the continuity between children's participations in Old Covenant feasts and the New Covenant meal as well as warn against misunderstanding Paul's admonition to divisive Corinthian church members.
Meyers also outlines the history of the practice in the church, showing how certain theological distortions like transubstantiation caused the practice of paedocommunion to fall away in the Western church as well as how to make distinctions between baptized members and voting members.
The "Answers in an Hour" series is an ongoing collection of short and easily digestible books written with the inquirer in mind. These little books provide brief studies of various topics of interest to Christians who seek instruction that is grounded in biblical theology.
