One of the most serious functions which the Presbyterian clergymen of Scotland had formerly to discharge was that of publicly examining their congregation in their knowledge of the Christian faith. Provided with a list of the congregation, the officiating minister in the pulpit proceeded to call up the members to answer questions out of the Shorter Catechism, or such other interrogatories as it might seem desirable to ask. Nobody knew when his turn would come, or what questions would be put to him, so that it was a time of trial and trepidation for old and young. The custom appears to be now obsolete, but reminiscences of its operation are still preserved. [Sidenote: ‘WHAT IS A SACRAMENT?’] An elderly minister was asked to take the catechising of the congregation in a parish in the pastoral uplands of the South of Scotland. He was warned against the danger of putting questions to a certain shepherd, who had made himself master of more divinity than some of his clerical contemporaries could boast, and who enjoyed nothing better than, out of the question put to him, to engage in an argument with the minister on some of the deepest problems of theology. The day of the ordeal at last came, the old doctor ascended the pulpit, and after the preliminary service put on his spectacles and unfolded the roll of the congregation. To the utter amazement of everybody, he began with the theological shepherd, John Scott. Up started the man, a tall, gaunt, sunburnt figure, with his maud over his shoulder, his broad blue bonnet on the board in front of him, and such a look of grim determination on his face as showed how sure he felt of the issue of the logical encounter to which he believed he had been challenged from the pulpit. The minister, who had clearly made up his mind as to the line of examination to be followed with this pugnacious theologian, looked at him calmly for a few moments, and then in a gentle voice asked, ‘Wha made you, John?’ The shepherd, prepared for questions on some of the most difficult points of our faith, was taken aback by being asked what every child in the parish could answer. He replied in a loud and astonished tone, ‘Wha made _me_?’ ‘It was the Lord God that made you, John,’ quietly interposed the minister. ‘Wha redeemed you, John?’ Anger now mingled with indignation as the man shouted, ‘Wha redeemed _me_?’ The old divine, still in the same mild way, reminded him ‘It was the Lord Jesus Christ that redeemed you, John,’ and then asked further, ‘Wha sanctified you, John?’ Scott, now thoroughly aroused, roared out, ‘Wha sanctified ME?’ The clergyman paused, looked at him calmly, and said, ‘It was the Holy Ghost that sanctified you, John Scott, if, indeed, ye be sanctified. Sit ye doon, my man, and learn your questions better the next time you come to the catechising.’ The shepherd was never able to hold his head up in the parish thereafter.
