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 participation in Old Covenant feasts and the New Covenant meal. He also warns against misunderstanding Paul's admonition in 1 Corinthians 11 to divisive church members.
In addition, Meyers outlines the history of the practice of paedocommunion in the church, showing how certain theological distortions like transubstantiation caused the practice to fall away in the Western church as well as how to make distinctions between baptized members and voting members.
