30. "All Theistic churches will shortly merge in the one eternal spiritual community by the grace of the Supreme Lord Shree Krishna Chaitanya"

Thakur Bhaktivinode's greatest gift to the world consists in this; that he has brought about the appearance of those pure devotees who are, at present, carrying on the movement of unalloyed devotion to the Feet of Shree Krishna by their own wholetime spiritual service of the Divinity. The purity of the soul is only analogously describable by the resources of the mundane language. The highest ideal of empiric morality is no better than the grossest wickedness to the Transcendental perfect purity of the bonafide devotee of the Absolute. The word 'morality' itself is a mischievous misnomer when it is applied to any quality of the conditioned soul. The hypocritical contentment with a negative attitude is part and parcel of the principle of undiluted immorality.

Those who pretend to recognise the Divine Mission of Thakur Bhaktivinode without aspiring to the unconditional service of those pure souls who really follow the teachings of the Thakur by the method enjoined by the scriptures and explained by Thakur Bhaktivinode in a way that is so eminently suited to the requirements of the sophisticated mentality of the present Age, only deceive themselves and their willing victims by their hypocritical professions and performances. These persons must not be confounded with the bonafide members of the flock.

Thakur Bhaktivinode has predicted the consummation of religious unity of the world by the appearance of the only universal church which bears the eternal designation of the Brahma Sampradaya. He has given mankind the blessed assurance that all Theistic churches will shortly merge in the one eternal spiritual community by the grace of the Supreme Lord Shree Krishna Chaitanya. The spiritual community is not circumscribed by the conditions of time and space, race and nationality. Mankind had been looking forward to this far-off Divine Event through the Long Ages. Thakur Bhaktivinode has made the conception available in its practicable spiritual form to the open minded empiricist who is prepared to undergo the process of enlightenment. The key stone of the Arch has been laid which will afford the needed shelter to all awakened animation under its ample encircling arms. Those who would thoughtlessly allow their hollow pride of race, pseudo-knowledge or pseudo-virtue to stand in the way of this long hoped for consummation, would have to thank only themselves for not being incorporated in the spiritual society of all pure souls.

These plain words need not be misrepresented, by arrogant persons who are full of the vanity of empiric ignorance, as the pronouncements of aggressive sectarianism. The aggressive pronouncement of the concrete Truth is the crying necessity of the moment for silencing the aggressive propaganda of specific untruths that is being carried on all over the world by the preachers of empiric contrivances for the amelioration of the hard lot of conditioned souls. The empiric propaganda clothes itself in the language of negative abstraction for deluding those who are engrossed in the selfish pursuit of worldly enjoyment.
