Shorter Catechism Illustration:  They must examine themselves

            During the ministry of Andrew Gray at Glasgow, William Guthrie of Fenwick on one occasion assisted him at the dispensation of the Lord’s Supper. Some of Cromwell’s officers, then in Glasgow, acting on the principle of promiscuous admission to the Lord’s table, were coming irregularly without having acquainted the minister, or giving evidence that they were prepared for the observance of that holy ordinance. Guthrie addressed them when leaving their pews to come to the table, with such gravity, resolution and zeal that they were quite confounded, and sat down again, without causing any further disturbance.

Shorter Catechism Scriptures

But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.       — 1 Corinthians 11:28, 29

Examine yourselves, whether ye be in the faith: prove your own selves: know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?         — 2 Corinthians 13:5

For if we would judge ourselves, we should not be judged.
                                                                — 1 Corinthians 11:31

Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. — 1 Corinthians 5:7, 8
