Acts iii. 19, is a good text to use with Roman Catholics as it shows the necessity of repentance and conversion. What repentance is, will be shown by Is. lv. 7; Jonah iii. 10. Still another way of dealing with Roman Catholics is by showing them that it is the believer’s privilege to know that he has eternal life. Roman Catholics almost always lack assurance. They do not know that they are forgiven, but hope to be forgiven some day. If you can show them that we may _know_ that we are forgiven and that we have eternal life, it will awaken in a great many of them a desire for this assurance. 1 John v. 13, shows that it is the believer’s privilege to know. Acts xiii. 38, 39; x. 43, John iii. 36, are very useful in leading them into this assurance. Still another way of dealing with them (but it is not best to use it until you have already made some progress with them) is to show them the advantage of Bible study. Good texts for this purpose are John v. 39; 1 Peter ii. 1, 2; 2 Tim. iii. 13‒17; Jas i. 21, 22; Ps. i. 1, 2; Josh. i. 8; Mark vii. 7, 8, 13; Matt. xxii. 29. These texts, excepting the one in 1 Peter ii. 1, 2, are all practically the same in the “Douay” or Roman Catholic Bible as they are in the Protestant Bible and it is well oftentimes in dealing with a Catholic to use the Catholic Bible. Still another way of dealing with a Roman Catholic is to use the same method that you would in dealing with an impenitent sinner—that is to awaken a sense that he is a sinner and needs Christ. For this purpose use Matt. xxii. 37, 38; Gal. iii. 10, 13; Is. liii. 6. Many people think that there is no use of talking with Roman Catholics, that they cannot be brought to Christ. This is a great mistake. Many of them are longing for something they do not find in the Roman Catholic church, and, if you can show them from the word of God how to find it, they come along very easily and they make very earnest Christians. Do not attack the Roman Catholic church. Give them the truth, and the errors in time will take care of themselves. Often times our attacks only expose our ignorance. There is one point at which we always have the advantage in dealing with a Roman Catholic; that is that there is peace and power in Christianity as we know it that there is not in Christianity as they know it, and they appreciate the difference.
