Isles have all been talking of doing; and some of the godly people of India have already entered upon the work. THE MAHOMEDAN ANSWER TO THE QUESTION. Brother disciple of the Koran, will you please to tell us what the one hundred and fifty million of followers of the great prophet believe is necessary to do and believe in order to be saved? "Yes, certainly. The devout believers in this soul-saving religion have understood this question for more than a thousand years, and know exactly how to answer it. You must believe that the Holy Book (the Koran) is God's last revelation, and his last will and testament to mankind; and you must shape your practical lives by its precepts, which will make you 'true saints,' and honest, upright, and righteous men and women. You must also believe that the great prophet is the true, holy, and appointed messenger of God, and that Allah is the only true God. To believe, as Christians do, that God is divided into three persons or beings, or three attributes, or three branches, known as Father, Son, and Holy Ghost, is not only a monstrous absurdity, but a monstrous sin and an unpardonable blasphemy; and no man or woman who holds such doctrine can be saved. God is but one, and Allah is his name, and you must worship him seven times a day; and on the sabbath day (Friday) you must present yourselves at the mosque with the Holy Book in your hand, which, having kissed, you are then to place it upon the holy altar, and listen while the priest explains its great truths and its profound and godly mysteries." And "on such occasions," says Major Denham, "tears flow in abundance, as under Christian preaching." Here, then, you have the terms of salvation and the road marked cut to heaven by the believers in the Koran. THE CHRISTIAN CHURCHES' ANSWER TO THE QUESTION. And now, brethren of the Christian faith, we will listen with attention to your answer to the important question, "What shall we do and believe in order to be saved?" But Christian sects are so numerous, and their views so conflicting, we can only find room for the answers of a few of the leading churches. THE CATHOLIC'S ANSWER. Well, brother Roman Catholic, as you represent the oldest Christian denomination in existence, we will first hear from your Church in answer to this great question, "What shall we do and believe in order to be saved?"--"Well, the question is easily answered. You must believe that the Bible is the inspired word of God; that Jesus Christ is the son of God; and that St. Peter, succeeded by the Pope, is his vicegerent on the earth. You must also worship, or at least believe in the divinity of, the Father, son, and Holy Ghost, and the Virgin Mary; and adhere to the various rites and ceremonies of the Church."
