176. So what should precede the participation in the Lord’s supper?
The celebration of the Lord’s Supper presupposes a self-examination to see if we are still holding onto any known sin, whether our faith in Christ and our love for God are heartfelt, whether our relationship with our neighbour is right – that we treat him in a forgiving, patient and compassionate way.
Let a man examine himself, and so let him eat of the bread and drink of the cup. For he who eats and drinks in an unworthy manner eats and drinks judgment to himself. (1 Corinthians 11:28-29)
Examine yourselves as to whether you are in the faith. (2 Corinthians 13:5)
Be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you. (Ephesians 4:32)
For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive your trespasses. (Matthew 6:14-15)
Therefore if you bring your gift to the altar, and there remember that your brother has something against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift. (Matthew 5:23-24)
