I came to the conclusion long ago… that all religions were true and also that all had some error in them, and whilst I hold by my own, I should hold others as dear as Hinduism. So we can only pray, if we are Hindus, not that a Christian should become a Hindu… But our innermost prayer should be a Hindu should be a better Hindu, a Muslim a better Muslim, a Christian a better Christian.
Mohandas Gandhi (Hinduism)
Basically all major religions of the world carry the same message; therefore harmony between different religions is both important and necessary.
Each system has its own value suited to persons of different disposition and mental outlook. At this time of easy communication, we must increase our efforts to learn each other’s system. This does not mean that we should make all religions into one but that we should recognize the common purpose of the many religions and value the different techniques that they have developed for internal improvement.
Tenzin Gyatso, The Fourteenth Dalai Lama (Buddhism)
The Church therefore has this exhortation for her sons: prudently and lovingly, through dialogue and collaboration with the followers of other religions, and in witness of Christian faith and life, acknowledge, preserve, and promote the spiritual and moral goods found among these men, as well as the values in their society and culture.
Vatican II, Nostra Aetate (Christianity)
My house shall be called a house of prayer for all peoples.
And I [Jesus] have other sheep, that are not of this fold; I must bring them also, and they will heed my voice. So there shall be one flock, one shepherd.
The essential purpose of the religion of God is to establish unity among mankind. The divine Manifestations were Founders of the means of fellowship and love. They did not come to create discord, strife and hatred in the world. The religion of God is the cause of love, but if it is made to be a source of enmity and bloodshed, surely its absence is preferable to its existence; for then it becomes satanic, detrimental and an obstacle to the human world…It is our duty in this radiant century to investigate the essentials of divine religion, seek the realities underlying the oneness of the world of humanity, and discover the source of fellowship and agreement which will unite mankind in the heavenly bond of love. This unity is the radiance of eternity, the divine spirituality, the effulgence of God and the bounty of the Kingdom.
