MY DEAR BROTHER,--The mutual relation existing between us, as members of the same Synod, the glory of our common Lord, the interests of our Mission, and a sacred regard for personal character, all require, that the following statement be transmitted to you and my other co-presbyters, with as little delay as possible. If I am not actuated herein by a desire to promote God's glory and the salvation of men, may the Lord rebuke and forgive me, and "let the righteous smite me, it shall be a kindness!" May the Head of the Church grant to you, and to all the other members of Synod, a disposition to hear, with patience and candor, a narration of my recent experience, in which perhaps you _may_ find things both "new and old." My sentiments in relation to the "Sabbath of the Lord our God," have undergone an important change; to which I now wish to call your attention. Our Confession of Faith, Catechisms, and Testimony, all teach that the first day of the week is, and has been ever since the resurrection of Christ, the Christian Sabbath. This doctrine _alone_, of all those contained in our Standards, though I did believe it till lately, I can no longer receive. As to the _manner_ of sanctifying the Sabbath, I believe all that you and I have always contended for; but, for the present, I am constrained to believe, that the seventh day of the week is the only weekly Sabbath that God has ever appointed. My attention was first called to this subject by Rev. W. M. Jones, Missionary of the Baptist Church, who has recently abandoned his earlier views and practice in regard to the Sabbath. He not only argued the question with me at length, but gave me some publications of the American Sabbath Tract Society, which, as they seemed to breathe a spirit of ardent piety and zeal for God's law, I read with attention. Both in my discussion with him, and in the reading of those tracts, I struggled with all my might to convince myself, from the Scriptures, of the divine appointment of the first-day, or Christian Sabbath. But though I did not then doubt it, I was astonished to find how hard it is to prove it.
