Christendom its Unity and Diversify. By the Rev. Jardine Wallace.

(W. Blackwood and Sons. ld.)-This is a reprint of a sermon first preached in 1870, a vigorous discourse in which a great truth is clearly stated and emphatically defended. Scotland supplies what is in some respects a highly significant illustration of the thesis. It certainly can show what is perhaps the most important movement in the direction of unity that has been seen since the Reformation. Mr. Wallace, as a minister of the Established Church, is not directly affected by this movement, but he may well see in it a testimony to the principles which he lays down. His application would go much further; nor does he regard external union as necessary. In any case, such pronounce- ments as his must always have their value.
