The Greek word apostasia indicates a “falling away” from the truth, especially true religion (see 2 Thes. 2:1-3). That having been said, it seems perhaps more accurate to say that true apostasy is more of a “turning away” or “turning against” than a mere passive departure through neglect. “Perhaps even more accurately, apostasy could be described as a particular group turning its back on God or rejecting the covenant relationship offered through His household (2 Chronicles 29:6; Jeremiah 2:27). Accordingly, apostasy is not necessarily a desertion from religion itself but rather a perversion of, or a rebellion against, true religion. Thus, apostasy does not require total departure from one’s faith but rather a rejection of God’s laws and His prophets or divinely appointed leadership” (Where Have All the Prophets Gone? p. 19).

“Biblical and historical evidence suggest that general apostasy is not necessary for God to introduce a new dispensation, although it sometimes happens that way. Just as apostasy can be seen as a deviation from the true course, so can a dispensation be seen as a course correction. Put another way, sometime divine reordering is necessary to correct both the orientation and the operation of the household of God” (Prophets, p. 19).

With the reordering of God’s affairs and the calling of a new founding prophet to head a new dispensation, four significant problems are overcome: (1) a living prophet is reestablished as the spokesman for God on earth, through whom our Father speaks to His children; (2) God’s divine authority that enables man to act in God’s name and lead His people is reestablished; (3) distorted doctrines are clarified and restored to their simple and pure state; and (4) the authority to perform sacraments, or rites and ordinances, is restored, along with the true nature of their purpose.
