The problem addressed in this study relates to the different approaches adopted by various Abrahamic Faith religions with regard to the philosophy of religious asceticism with the primary goal of achieving spiritual growth. Douglas (18) noted that even though the meaning of asceticism in all the three Abrahamic Faith religions was the same, the practice of asceticism differed significantly among from each other, with the Christians, Judaism and Muslims observing different practices altogether. Similarly, Taliaferro and Elsa (17) established that the choice of an asceticism practice was depended in the religious doctrines and beliefs of a particular Abrahamic religion, which in turn brought about the differences. This is with regard to the fact even though all religions traced their roots to one common founding father, Abraham; they practiced different beliefs and practices. Podmore (439) noted that Christianity draws its foundation from Isaac, the son of Abraham, from whose lineage Jesus Christ was born. On the other hand, Islam draws its foundation from Ishmael, also another son of Abraham, from whose lineage the holy Prophet Mohammad was born. Jesus is the founder of the Christianity religion while Mohammad is the founder of the Islamic religion. Judaism reflects the religion practiced by the Jewish people, given that they were the Children of Israel, with whom God entered into a holy covenant as noted in the Old Testament part of the bible (Nadler 12). Apparently, both Islamic and Christianity religions share the same teachings from the Old Testament, but the split in their religion comes in the New Testament, whereby Christians go the Jesus Christ’s way while Muslims go the Prophet Mohammad’s way. In this regard, the research study evaluates the different practices of asceticism observed by each of the three Abrahamic Faith religions in order to develop a theological and philosophical perspective of asceticism as a means of achieving religious piety.
