'The deep mid-channel of the Church's course': a late 19th century Old High vision of Deep Anglicanism

In his 1872 primary visitation charge, William Connor Magee, Bishop of Peterborough, had - as previous posts explored - robustly critiqued Anglo-papalism, neo-Puritan evangelicalism, and advanced liberalism. He goes on, however, to provide a significant and powerful account of what we might term 'Deep Anglicanism', in which the three streams - High, Low, and Broad - mutually enrich each other, all part of "the deep mid-channel of the Church's course":

In truth, each of these parties, little as it might be disposed to own it, has learned, is learning, much from the other two. There is more of Evangelicalism in the High Churchman, more of High Church principle in the Evangelical, more of Dogma in the Broad Churchman than would flow from their own avowed principles but which comes for each from the influence of those to whom he is most opposed. Candid and earnest men of all parties are learning to recognize this more and more; are coming to understand that it is not given to any one School, or to any one Age, any more than to any one man, to see truth on all sides; but that it is rather by the assertion, the necessarily one-sided assertion, of different aspects of truth, that the whole body of the truth can be preserved. And so each comes in turn, not only to endure, but to value the presence of the other in the Church, to feel that there is an appointed and an important work for each one of them to do, which can be done by that one only. And thus while extreme men on either side are pushing their views to extreme lengths, standing as far apart as possible, denouncing each other so loudly and so bitterly, that it might be thought the Church must speedily be torn asunder by their strife, the Church herself — larger, wider, greater than any one of the parties within her — may be gaining from their very strife a larger and a firmer grasp of the truths of which she is the guardian — a clearer perception of the limits beyond which her children may not safely stray; the very errors and excesses of each party, their very shipwrecks of the Faith, sad as they are to see, serving to buoy out on the right hand and on the left the deep mid-channel of the Church's course. It is to this growth of a sound and loyal Churchmanship — taught in turn and learned in turn by each of the great parties in our Church — that we must look under God for her safe passage through the troubled waters on which she is now tossing.
