A very hopeful fact in the missions to Oriental Churches, has been the number of able men affected by the truth. Eminently such was a learned Greek Catholic of Damascus, named Michael Meshakah, who became convinced of the errors of his Church, and openly declared himself a Protestant in 1848. He had embraced infidel views to quiet his conscience, but the reading of "Keith on the Prophecies" in Arabic, and other books from the mission presses, especially the Scriptures, led him to relinquish these, and personal intercourse with missionaries, especially with Dr. Smith, induced him to take a decided stand for Christ. He used no reserve in professing his attachment to the gospel. This brought on a controversy between him and his Patriarch, and as he was esteemed the most intelligent native layman in the country, and the Patriarch the most learned ecclesiastic, attention from all quarters was directed to their debate. Having decided to publish the reasons of his secession from the Catholic Church, and to prove the corruptness of the doctrines and practices in that Church, he commenced a free and full correspondence with Dr. Smith in Arabic. The result was a treatise, which was published by the mission. After making the reader acquainted with his own history, he disproved the supremacy of the Pope, the existence of any priesthood but that of Christ, or of any atonement but his. He then showed that there was no authority for more than two grades of officers in the church, or for the doctrine of transubstantiation. There were, also, chapters on justification by faith and the new birth. Dr. Smith declares the treatise to have been "well and thoroughly argued, sometimes most impressively solemn, at others keenly sarcastic, and spirited and fearless throughout."1 1 The _Bibliotheca Sacra_, for October, 1858, contains an account of Dr. Meshakah by Dr. Thomas Laurie, and a translation of a treatise by him on skepticism.
