Westminster Larger Catechism – Lord’s Day 43
Q & A 171
Q How are they that receive the sacrament of the Lord’s Supper to prepare themselves before they come unto it?
A They that receive the sacrament of the Lord’s Supper are, before they come, to prepare themselves thereunto, by examining themselves of their being in Christ, of their sins and wants; of the truth and measure of their knowledge, faith, repentance; love to God and the brethren, charity to all men, forgiving those that have done them wrong; of their desires after Christ, and of their new obedience; and by renewing the exercise of these graces, by serious meditation, and fervent prayer.
Q & A 172
Q May one who doubts of his being in Christ, or of his due preparation, come to the Lord’s Supper?
A One who doubts of his being in Christ, or of his due preparation to the sacrament of the Lord’s Supper, may have true interest in Christ, though he be not yet assured thereof; and in God’s account has it, if he be duly affected with the apprehension of the want of it, and unfeignedly desires to be found in Christ, and to depart from iniquity: in which case (because promises are made, and this sacrament is appointed, for the relief even of weak and doubting Christians) he is to bewail his unbelief, and labor to have his doubts resolved; and, so doing, he may and ought to come to the Lord’s Supper, that he may be further strengthened.
Q & A 173
Q May any who profess the faith, and desire to come to the Lord’s Supper, be kept from it?
A Such as are found to be ignorant or scandalous, notwithstanding their profession of the faith, and desire to come to the Lord’s Supper, may and ought to be kept from that sacrament, by the power which Christ has left in his church, until they receive instruction, and manifest their reformation.
Q & A 174
Q What is required of them that receive the sacrament of the Lord’s Supper in the time of the administration of it?
A It is required of them that receive the sacrament of the Lord’s Supper, that, during the time of the administration of it, with all holy reverence and attention they wait upon God in that ordinance, diligently observe the sacramental elements and actions, heedfully discern the Lord’s body, and affectionately meditate on his death and sufferings, and thereby stir up themselves to a vigorous exercise of their graces; in judging themselves, and sorrowing for sin; in earnest hungering and thirsting after Christ, feeding on him by faith, receiving of his fulness, trusting in his merits, rejoicing in his love, giving thanks for his grace; in renewing of their covenant with God, and love to all the saints.
Q & A 175
Q What is the duty of Christians, after they have received the sacrament of the Lord’s Supper?
A 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; if they find quickening and comfort, to bless God for it, beg the continuance of it, watch against relapses, fulfil their vows, and encourage themselves to a frequent attendance on that ordinance: but if they find no present benefit, more exactly to review their preparation to, and carriage at, the sacrament; in both which, if they can approve themselves to God and their own consciences, they are to wait for the fruit of it in due time: but, if they see they have failed in either, they are to be humbled, and to attend upon it afterwards with more care and diligence.
