4. The fourth note of the Church here implied is its unity. The Lord of all the Churches is one Lord; in this allegiance they centre, and by it are held together in a true unity. Plainly this note can belong only to the Church invisible, and not to that multifarious collection of incoherent fragments known as the visible Church. It is indeed doubtful whether a visible unity is desirable. Considering what human nature is and how liable men are to be overawed and imposed upon by what is large, it is probably quite as conducive to the spiritual well-being of the Church that she is broken up into parts. Outward divisions into national Churches and Churches under different forms of government and holding various creeds would sink into insignificance, and be no more bewailed than the division of an army into regiments, were there the real unity which springs from true allegiance to the common Lord and zeal for the common cause rather than for the interests of our own particular Church. When the generous rivalry exhibited by some of our regiments in battle passes into envy, unity is destroyed; and indeed the attitude sometimes assumed towards sister-Churches is rather that of hostile armies than of rival regiments striving which can do most honour to the common flag. One of the hopeful signs of our times is that this is generally understood. Christian people are beginning to see how much more important are those points on which the whole Church is agreed than those often obscure or trivial points which split the Church into sects. Churches are beginning to own with some sincerity that there are Christian gifts and graces in all Churches, and that no one Church comprises all the excellences of Christendom. And the only outward unity that is worth having is that which springs from inward unity, from a genuine respect and regard for all who own the same Lord and spend themselves in His service.
