“Love of God implies love of religion. And religion exemplifies that creative spirit of God which is at work in history as well as in the mind of man. Thus, one ought to love any religion, that is, religion as such, and in any form—as a manifestation of the moral spirit, the divine spirit of mankind.”

An Humble, Earnest and Affectionate Address to the Clergy (1761)
Context: God could not make the creature to be great and glorious in itself; this is as impossible, as for God to create beings into a state of independence on himself. "The heavens," saith David, "declare the glory of God"; and no creature, any more than the heavens, can declare any other glory but that of God. And as well might it be said, that the firmament shows forth its own handiwork, as that a holy divine or heavenly creature shows forth its own natural power.
But now, if all that is divine, great, glorious, and happy, in the spirits, tempers, operations, and enjoyments of the creature, is only so much of the greatness, glory, majesty, and blessedness of God, dwelling in it, and giving forth various births of his own triune life, light, and love, in and through the manifold forms and capacities of the creature to receive them, then we may infallibly see the true ground and nature of all true religion, and when and how we may be said to fulfill all our religious duty to God. For the creature's true religion, is its rendering to God all that is God's, it is its true continual acknowledging all that which it is, and has, and enjoys, in and from God. This is the one true religion of all intelligent creatures, whether in heaven, or on earth; for as they all have but one and the same relation to God, so though ever so different in their several births, states or offices, they all have but one and the same true religion, or right behavior towards God. Now the one relation, which is the ground of all true religion, and is one and the same between God and all intelligent creatures, is this, it is a total unalterable dependence upon God, an immediate continual receiving of every kind, and degree of goodness, blessing and happiness, that ever was, or can be found in them, from God alone. The highest angel has nothing of its own that it can offer unto God, no more light, love, purity, perfection, and glorious hallelujahs, that spring from itself, or its own powers, than the poorest creature upon earth. Could the angel see a spark of wisdom, goodness, or excellence, as coming from, or belonging to itself, its place in heaven would be lost, as sure as Lucifer lost his. But they are ever abiding flames of pure love, always ascending up to and uniting with God, for this reason, because the wisdom, the power, the glory, the majesty, the love, and goodness of God alone, is all that they see, and feel, and know, either within or without themselves. Songs of praise to their heavenly Father are their ravishing delight, because they see, and know, and feel, that it is the breath and Spirit of their heavenly Father that sings and rejoices in them. Their adoration in spirit and in truth never ceases, because they never cease to acknowledge the ALL of God; the ALL of God in the whole creation. This is the one religion of heaven, and nothing else is the truth of religion on earth.

Context: The plain fact is that men's minds are built, as has been often said, in water-tight compartments. Religious after a fashion, they yet have many other things in them beside their religion, and unholy entanglements and associations inevitably obtain. The basenesses so commonly charged to religion's account are thus, almost all of them, not chargeable at all to religion proper, but rather to religion's wicked practical partner, the spirit of corporate dominion. And the bigotries are most of them in their turn chargeable to religion's wicked intellectual partner, the spirit of dogmatic dominion, the passion for laying down the law in the form of an absolutely closed-in theoretic system. The ecclesiastical spirit in general is the sum of these two spirits of dominion.

Notes from Devotional Authors of the Middle Ages (1873-1874)
Context: That Religion is not devotion, but work and suffering for the love of God; this is the true doctrine of Mystics — as is more particularly set forth in a definition of the 16th century: "True religion is to have no other will but God's." Compare this with the definition of Religion in Johnson's Dictionary: "Virtue founded upon reverence of God and expectation of future rewards and punishments"; in other words on respect and self-interest, not love. Imagine the religion which inspired the life of Christ "founded" on the motives given by Dr. Johnson!
Christ Himself was the first true Mystic. "My meat is to do the will of Him that sent me and to finish His work." What is this but putting in fervent and the most striking words the foundation of all real Mystical Religion? — which is that for all our actions, all our words, all our thoughts, the food upon which they are to live and have their being is to be the indwelling presence of God, the union with God; that is, with the Spirit of Goodness and Wisdom.

Context: Spirit is knowledge; but in order that knowledge should exist; it is necessary that the content of that which it knows should have attained to this ideal form, and should in this way have been negated. What Spirit is must in that way have become its own, it must have described this circle; then these forms, differences, determinations finite qualities, must have existed in order that it should make them its own. This represents both the way and the goal-that Spirit should have attained to its own notion or conception, to that which it implicitly is, and in this way only, the way which has been indicated in its abstract moments, does it attain it. Revealed religion is manifested religion, because in it God has become wholly manifest. Here all is proportionate to the notion; there is no longer anything secret in God.
