Excerpts from Theodore Parker's sermon, "The Transient and Permanent in Christianity," delivered at the Ordination of Rev. Charles C. Shackford in the Hawes Place Church, Boston on May 19, 1841.

... Looking at the Word of Jesus, at real Christianity, the pure religion he taught, nothing appears more fixed and certain. Its influence widens as light extends; it deepens as the nations grow more wise. But, looking at the history of what men call Christianity, nothing seems more uncertain and perishable. While true religion is always the same thing, in each century and every land, in each man that feels it, the Christianity of the Pulpit, which is the religion taught; the Christianity of the People, which is the religion that is accepted and lived out; has never been the same thing in any two centuries or lands, except only in name...

(Pause.)

Let us look at this matter a little more closely. In actual Christianity -- that is, in that portion of Christianity which is preached and believed -- there seem to have been, ever since the time of its earthly founder, two elements, the one transient, the other permanent. The one is the thought, the folly, the uncertain wisdom, the theological notions, the impiety of man; the other, the eternal truth of God. These two bear perhaps the same relation to each other that the phenomena of outward nature, such as sunshine and cloud, growth, decay, and reproduction, bear to the great law of nature, which underlies and supports them all...

(Pause.)

An undue place has often been assigned to forms and doctrines, while too little stress has been laid on the divine life of the soul, love to God, and love to man...

Now there can be but one Religion which is absolutely true, existing in the facts of human nature, and the ideas of Infinite God. That, whether acknowledged or not, is always the same thing and never changes. So far as a man has any real religion -- either the principle or the sentiment thereof -- so far he has that, by whatever name he may call it. For, strictly speaking, there is but one kind of religion, as there is but one kind of love, though the manifestations of this religion, in forms, doctrine, and life, be never so diverse. It is through these, men approximate to the true expression of this religion. Now while this religion is one and always the same thing, there may be numerous systems of theology or philosophies of religion...

(Pause.)

Any one, who traces the history of what is called Christianity, will see that nothing changes more from age to age than the doctrines taught as Christian, and insisted on as essential to Christianity and personal salvation. What is falsehood in one province passes for truth in another. The heresy of one age is the orthodox belief and "only infallible rule" of the next...

(I)f we are faithful, the great truths of morality and religion, the deep sentiment of love to man and love to God, are perceived intuitively, and by instinct, as it were, though our theology be imperfect and miserable...

(Pause.)

Almost every sect, that has ever been, makes Christianity rest on the personal authority of Jesus, and not the immutable truth of the doctrines themselves, or the authority of God, who sent him into the world. Yet it seems difficult to conceive any reason, why moral and religious truths should rest for their support on the personal authority of their revealer, any more than the truths of science on that of him who makes them known first or most clearly. It is hard to see why the great truths of Christianity rest on the personal authority of Jesus, more than the axioms of geometry rest on the personal authority of Euclid, or Archimedes. The authority of Jesus, as of all teachers, one would naturally think, must rest on the truth of his words, and not their truth on his authority...

Now it seems clear, that the notion men form about the origin and nature of the scriptures; respecting the nature and authority of Christ, have nothing to do with Christianity except as its aids or its adversaries; they are not the foundation of its truths ...

(Pause.)

(Jesus) was the organ through which the Infinite spoke. It is God that was manifested in the flesh by him, on whom rests the truth which Jesus brought to light and made clear and beautiful in his life; and if Christianity be true, it seems useless to look for any other authority to uphold it, as for some one to support Almighty God. So if it could be proved, -- as it cannot, -- in opposition to the greatest amount of historical evidence ever collected on any similar point, that the gospels were the fabrication of designing and artful men, that Jesus of Nazareth had never lived, still Christianity would stand firm, and fear no evil. None of the doctrines of that religion would fall to the ground; for if true, they stand by themselves. But we should lose, -- oh, irreparable loss! -- the example of that character, so beautiful, so divine, that no human genius could have conceived it, as none, after all the progress and refinement of eighteen centuries, seems fully to have comprehended its lustrous life...

(Pause.)

In (Jesus) the Godlike and the Human met and embraced, and a divine Life was born. Measure him by the world's greatest sons; -- how poor they are. Try him by the best of men, -- how little and low they appear. Exalt him as much as we may, we shall yet, perhaps, come short of the mark. But still was he not our brother; the son of man, as we are; the Son of God, like ourselves? His excellence, was it not human excellence? His wisdom, love, piety, -- sweet and celestial as they were, -- are they not what we also may attain? In him, as in a mirror, we may see the image of God, and go on from glory to glory, till we are changed into the same image, led by the spirit which enlightens the humble. Viewed in this way, how beautiful is the life of Jesus. Heaven has come down to earth, or rather, earth has become heaven. The Son of God, come of age, has taken possession of his birthright...

(Pause.)

Christianity itself, that pure Religion, which exists eternal in the constitution of the soul and the mind of God, is always the same. The Word that was before Abraham, in the very beginning, will not change, for that word is Truth. From this Jesus subtracted nothing; to this he added nothing. But he came to reveal it as the secret of God, that cunning men could not understand, but which filled the souls of men meek and lowly of heart...

(Pause.)

To turn away from the disputes of the Catholics and the Protestants, of the Unitarian and the Trinitarian, of Old School and New School, and come to the plain words of Jesus of Nazareth, Christianity is a simple thing; very simple. It is absolute, pure Morality; absolute, pure Religion; the love of man; the love of God acting without let or hindrance. The only creed it lays down is the great truth which springs up spontaneous in the holy heart -- there is a God. Its watchword is, be perfect as your Father in Heaven. The only form it demands is a divine life; doing the best thing, in the best way, from the highest motives; perfect obedience to the great law of God. Its sanction is the voice of God in your heart; the perpetual presence of Him, who made us and the stars over our head; Christ and the Father abiding within us. All this is very simple; a little child can understand it; very beautiful, the loftiest mind can find nothing so lovely. Try it by Reason, Conscience, and Faith -- things highest in man's nature -- we see no redundance, we feel no deficiency. Examine the particular duties it enjoins; humility, reverence, sobriety, gentleness, charity, forgiveness, fortitude, resignation, faith, and active love; try the whole extent of Christianity so well summed up in the command, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind -- thou shalt love thy neighbor as thyself;" and is there anything therein that can perish?...

Were all men Quakers or Catholics, Unitarians or Baptists, there would be much less diversity of thought, character, and life; less of truth active in the world than now. But Christianity gives us the largest liberty of the sons of God, and were all men Christians after the fashion of Jesus, this variety would be a thousand times greater than now; for Christianity is not a system of doctrines, but rather a method of attaining oneness with God...

(Pause.)

The truths he taught; his doctrines respecting man and God; the relation between man and man, and man and God, with the duties that grow out of that relation, are always the same, and can never change till man ceases to be man, and creation vanishes into nothing...

For it is not so much by the Christ who lived so blameless and beautiful eighteen centuries ago, that we are saved directly, but by the Christ we form in our hearts and live out in our daily life, that we save ourselves, God working with us, both to will and to do...

God send us a real religious life, which shall pluck blindness out of the heart, and make us better fathers, mothers, and children; a religious life, that shall go with us where we go, and make every home the house of God, every act acceptable as a prayer...
