As I have already intimated in the course of my conversations with visiting pilgrims, so vast and significant an enterprise as the construction of the first Mashriqu’l-Adhkár of the West should be supported, not by the munificence of a few but by the joint contributions of the entire mass of the convinced followers of the Faith. It cannot be denied that the emanations of spiritual power and inspiration destined to radiate from the central Edifice of the Mashriqu’l-Adhkár will to a very large extent depend upon the range and variety of the contributing believers, as well as upon the nature and degree of self-abnegation which their unsolicited offerings will entail. Moreover, we should, I feel, regard it as an axiom and guiding principle of Bahá’í administration that in the conduct of every specific Bahá’í activity, as different from undertakings of a humanitarian, philanthropic or charitable character, which may in future be conducted under Bahá’í auspices, only those who have already identified themselves with the Faith and are regarded as its avowed and unreserved supporters should be invited to join and collaborate. For apart from the consideration of embarrassing complications which the association of non-believers in the financing of institutions of a strictly Bahá’í character may conceivably engender in the administration of the Bahá’í community of the future, it should be remembered that these specific Bahá’í institutions, which should be viewed in the light of Bahá’u’lláh’s gifts bestowed upon the world, can best function and most powerfully exert their influence in the world only if reared and maintained solely by the support of those who are fully conscious of, and are unreservedly submissive to, the claims inherent in the Revelation of Bahá’u’lláh. […] Ours surely is the paramount duty so to acquit ourselves in the discharge of our most sacred task that in the days to come neither the tongue of the slanderer nor the pen of the malevolent may dare to insinuate that so beauteous, so significant an Edifice has been reared by anything short of the unanimous, the exclusive, and the self-sacrificing strivings of the small yet determined body of the convinced supporters of the Faith of Bahá’u’lláh.
