Q. 199. State the Communion Doctrine of the 1648 Westminster Larger Catechism 174-77. A. 199. Question 174 declares that those who properly "receive the Sacrament of the Lord’s Supper" – do so "with all holy reverence and attention. Leviticus 10:3; Hebrews 12:28; Psalm 10:7; First Corinthians 11:17,26-27." They must: "diligently observe the sacramental elements and actions (Exodus 24:8 & Matthew 16:28); heedfully discern the Lord’s body (First Corinthians 11:29); and affectionately meditate on His death and sufferings (Luke 22:19). Question 175 is even more difficult (if not impossible) of fulfillment – by one not yet even a teenager. For it declares that "the duty of Christians – after they have received the Sacrament of the Lord’s Supper – is seriously to consider how they have behaved themselves therein, and with what success…. First Corinthians 11:17,30,31." And, after Question 176 stresses the similarities between Baptism and the Lord’s Supper – Question 177 very clearly states "wherein" they "differ." Indeed, it rightly declares that whereas "Baptism is to be administered…even to infants" of the covenant – "the Lord’s Supper is to be administered…only to such as are of years and ability to examine themselves (First Corinthians 11:28-29)."
