Apostasy is generally seen as deviation from the orthodox faith. It is a highly derogatory term, indicating one who has relapsed spiritually and who will suffer because of it. In the traditional church, apostasy is treated as a disease, one which must be excised swiftly to prevent contamination of the rest of the body. Good church people react to apostasy like they would cancer or the plague. Liberal doses of orthodox theology, frequently applied, are considered the best preventative for apostates.
In the above scenario and way of thinking, deviations from essential church doctrines result from satanic influences. The Truth of the church is never rejected because it is confused, disjointed, and unfulfilling; instead men purportedly reject the church and its message because they are basically flawed and therefore blinded or willfully evil. The problem which prompts the apostate all reside in him of her. The church bears no responsibility for the ineffectiveness of its version of the Truth.
One needn't be very perceptive to notice how convenient this reasoning is for those who sponsor the church's doctrinal position. There is never anything to explain, re-evaluate, or change in the orthodox message. It's Truth becomes unchallengeable by definition and official sanction.
In those cases where people succeed in developing and embracing a personal faith, one they have not inherited by tradition and constant indoctrination, the idea of apostasy is incongruous. A personal faith cannot apostatize; it merely grows and evolves. A personal faith that fails to foster peace, joy, unity, and fulfillment is just quietly discarded until something better takes its place. Let the church wring its hands about apostates all they want, but many of those apostates enjoy a freedom they never could have experienced in the church. Once freedom is enjoyed, spiritual restriction is unbearable.
