"...that the supposed distinction between baptism as a sacrament of initiation and the Lord's Supper as a sacrament of nutrution, common in earlier Reformed materials, should be used as an argument against paedocommunion, seems to me both passing strange and powerful evidence of how uncritical the Reformed argument really was. Covenant children are to be nourished with the Word from their earliest days. By what principle would they not be given another means of their spiritual nourishment? This is a difficult question to answer for the Reformed who make a great deal of the intimate relationship between Word and sacrament and are often prepared to say that the sacrament is the Word of God in another form. By what principle, then, are our children to be given the sacrament that is the 'seal of the righteousness that is by faith' and to be given the Word of God (Gen 18:19; Deut. 6:6-9; Ps. 78:1-8), but are not to be given the visible word, the second sacrament, the sacrament that supposedly provides the nourishment of faith, especially since the spiritual feeding of children is a major theme in covenantal ethics?"
