The writer, and co-laborers, proclaimed the fact of the Lord's presence, demonstrating it from prophecy, and on charts or tables, such as are used in… - Charles Taze Russell

The reason for not attempting to purify the nominal systems is that no amount of cleansing would make the unconsecrated mass of "Christendom" and their organizations, civil and ecclesiastical, suitable to the Lord's work, now to be commenced on this earth. During the past eighteen centuries he has been selecting the truly consecrated, the worthy ones, and now all that remains to be done is to select from among the living those of the same class - and they are but few - as only a few are lacking to complete the fore-ordained number of members in the body of Christ.
The reason for discarding all human organizations, and not reforming the least objectionable one and calling out of all others into it, now, is shown by our Lord's treatment of the various Jewish sects in the harvest or close of their dispensation; for then, as now, all were rejected, and the "Israelites indeed" were called out of all, into freedom and taught the will and plan of God by various chosen vessels of God's own selection.

The feeling of uneasiness and insecurity, if not bound by the chains of some sect, is general. It is begotten of the false idea, first promulgated by Papacy, that membership in an earthly organization is essential, pleasing to the Lord and necessary to everlasting life. These earthly, humanly organized systems, so different from the simple, unfettered associations of the days of the apostles, are viewed involuntarily an almost unconsciously by Christian people as so many Heaven Insurance Companies, to some one of which money, time, respect, etc., must be paid regularly, to secure heavenly rest and peace after death. Acting on this false idea, people are almost as nervously anxious to be bound by another sect, if they step out of one, as they are if their policy of insurance has expired, to have it renewed in some respectable company.

Our Lord's new doctrines were the new wine, while the Jewish sects were the old wine-skins. Suppose that our Lord had joined one of those sects and had begun a reform in it: what would have been the result? There can be no doubt that the new truths, if received, would have broken up that sect completely. The power of its organization, built largely upon sectarian pride, and cemented by errors, superstitions and human traditions, would forthwith have been destroyed, and the new doctrines would have been left stranded - hampered, too, by all the old errors and traditions of that sect, and held responsible for its past record by the world in general.
