As fast as the life comes under the sway of the "kingdom of conscience" and a solid moral character is formed, the inner guidance of the Word of God becomes more certain and more reliable. Only the good person has a sure and unerring perception of the truth, just as only the scientist sees the laws of the world, and as only the musician perceives the harmony of sounds. Not only must all spiritual experience be subject to the moral test, it must further be tested by the Light of God in other men and in history, and by the _spirit of Scripture_, which is the noblest permanent fruit of the Eternal Word. Every person must _prove_ the authority of his religion. He must have his heart conquered and his mind taken captive and his will directed by his truth so that he would be ready to face a thousand deaths for it,[25] and he must, through his truth and insight, come into spiritual unity and co-operation with all who form the invisible Church. The invisible Church forms the central loyalty of Franck's fervent soul. "The true Church," he writes, "is not a separate mass of people, not a particular sect to be pointed out with the finger, not confined to one time or one place; it is rather a spiritual and invisible body of all the members of Christ, born of God, of one mind, spirit, and faith, but not gathered in any one external city or place. It is a Fellowship, seen with the spiritual eye and by the inner man. It is the assembly and communion of all truly God-fearing, good-hearted, new-born persons in all the world, bound together by the Holy Spirit in the peace of God and the bonds of love--a Communion outside of which there is no salvation, no Christ, no God, no comprehension of Scripture, no Holy Spirit, and no Gospel. I belong to this Fellowship. I believe in the Communion of saints, and I am in this Church, let me be where I may; and therefore I no {59} longer look for Christ in lo heres or lo theres."[26] This Church, which the Spirit is building through the ages and in all lands, is, once more, like the experience of the individual Christian, entirely an inward affair. "Love is the one mark and badge of Fellowship in it."[27] No outward forms of any sort seem to him necessary for membership in this true Church. "External gifts and offices make no Christian, and just as little does the standing of the person, or locality, or time, or dress, or food, or anything external. The kingdom of God is neither prince nor peasant, food nor drink, hat nor coat, here nor there, yesterday nor to-morrow, baptism nor circumcision, nor anything whatever that is external, but peace and joy in the Holy Spirit, unalloyed love out of a pure heart and good conscience, and an unfeigned faith."[28]
