EXPOSITION OF THE DOCTRINES OF GRACETHURSDAY, APRIL 11th, 1861.THE REV. C. H. SPURGEON TOOK THE CHAIR AT 3 o'clock. The REV. C. H. SPURGEON in opening the proceedings said, we have met together beneath this roof already to set forth most of those truths in which consists the peculiarity of this Church. Last evening we endeavoured to show to the world, that we heartily recognised the essential union of the Church of the Lord Jesus Christ. And now, this afternoon and evening, it is our intention, through the lips of our brethren, to set forth those things which are verily received among us, and especially those great points which have been so often attacked, but which are still upheld and maintained,--truths which we have proved in our experience to be full of grace and truth. My only business upon this occasion is to introduce the brethren who shall address you, and I shall do so as briefly as possible, making what I shall say a preface to their remarks.The controversy which has been carried on between the Calvinist and the Arminian is exceedingly important, but it does not so involve the vital point of personal godliness as to make eternal life depend upon our holding either system of theology.
