True religion is a firm belief in an Almighty Creator, in immortality, in self-perfection, in service, truth, love and compassion for all fellow beings, as the only way for the sanctification of human life to manifest the glory of the soul.

True religion is real living; living with all one's soul, with all one's goodness and righteousness.

I affirm, and would maintain, that true religion consists in proposing, as our great end, a growing likeness to the Supreme Being. Its noblest influence consists in making us more and more partakers of the Divinity. For this it is to be preached. Religious instruction should aim chiefly to turn men's aspirations and efforts to that perfection of the soul, which constitutes it a bright image of God. Such is the topic now to be discussed; and I implore Him, whose glory I seek, to aid me in unfolding and enforcing it with simplicity and clearness, with a calm and pure zeal, and with unfeigned charity.

The true religion is to be posited not in the knowledge or confession of what God allegedly does or has done for our salvation, but in what we must do to become worthy of this.

True Religion does not manifest itself outwardly, and impels man to no course of external conduct which he would not otherwise have adopted, but that it only completes his true In ward Being and Dignity. It is neither an Action, nor an incentive to Action, but a Thought:—it is LIGHT, and the One True Light, which bears within it all Life and all the forms of Life, and pervades their innermost substance. Once arisen, this Light flows on spontaneously forever, spreading itself forth without term or limit;-and it is as idle to bid it shine, as it would be to address such a command to the material sun when it stands in the noon-day heavens. It does this without our bidding; and if it shine not, then has it not arisen. At its uprising, Darkness, and the brood of spectres and phantasms which are born of Darkness, vanish of themselves.

The body of all true religion consists, to be sure, in obedience to the will of the Sovereign of the world, in a confidence in His declarations, and in imitation of His perfections.

But it is doubtless true, and evident from [the] Scriptures, that the essence of all true religion lies in holy love; and that in this divine affection, and an habitual disposition to it, and that light which is the foundation of it, and those things which are the fruits of it, consists the whole of religion.

What Spinoza regards as ‘true religion’ and ‘true piety’ requires no belief in any historical events, supernatural incidents or metaphysical doctrines, and it prescribes no devotional rites. It does not demand accepting any particular theology of God's nature or philosophical claims about the cosmos and its origins. The divine law directs us only on how to behave with justice and charity toward other human beings. ‘[We are] to uphold justice, help the helpless, do no murder, covet no man's goods, and so on’. All the other rituals or ceremonies of the Bible's commandments are empty practices that ‘do not contribute to blessedness and virtue’. True religion is nothing more than moral behaviour. It is not what you believe, but what you do that matters. Writing to the Englishman and secretary to the Royal Society Henry Oldenburg in 1675, Spinoza says that ‘the chief distinction I make between religion and superstition is that the latter is founded on ignorance, the former on wisdom’.

Religion can not be defined as belonging to any special faculty; and even reverence and worship are but local manifestations of the religious element, and can not be said to be true religion unless they extend through every department of the mind. Religion, properly considered, is that subtle agent of the soul which aspires to perfection in whatever way it is to be attained; and seeks to worship God because he is infinite, and is what man is for ever aspiring to become.

The true religion of Jesus Christ our Saviour is that which penetrates, and which receives all the warmth of the heart, and all the elevation of the soul, and all the energies of the understanding, and all the strength of the will.

There is a true, religious devotion in the mind and feelings of that man whose soul springs forth in beauty and power, whose physical form is upright and symmetrical, and who, in fulfilling the laws of health, fulfils the laws of Deity. There is a true religion in the intellectual man, who, penetrating deeply into the earth, and air, and sky, for scientific investigation, culls all the treasures of thought and beauty, and stores them up in his memory as sacred and divine.

True religion has, at its core: Love, Peace, Mercy, Justice and Freedom. If any of these elements is not fully present in a religion, the religion has been compromised.

No religion is absolutely perfect. Yet not only do we fight for religion, but also are we often willing to sacrifice our lives for it. And what we hopelessly fail to do is to live it. A true religion is that which has no caste, no creed, no colour. It is but an all-uniting and all-pervading embrace.

The spirit of true religion breathes gentleness and affability; it gives a native, unaffected ease to the behavior; it is social, kind, cheerful; far removed from the cloudy and illiberal disposition which clouds the brow, sharpens the temper, and dejects the spirit.
