The current study’s purpose is to explore the approach of philosophy of religious asceticism in the Abrahamic faith traditions. Harvey (12) defined asceticism as the type of lifestyle in which an individual, or a group of individuals, choose to abstain from sensual pleasures in favor of their spiritual growth and development. This means that ascetics tend to withdraw from the rest of the world, avoiding practices, cultures, or beliefs considered to bring about human pleasure, and instead opt for a frugal lifestyle whereby they practically renounce all forms of material possessions, physical pleasures, as well as social titles (Podmore 439). On the contrary, they spend their time in seclusion, fasting and concentrating on their religious practices, reflecting deeply in their spiritual matters. From a historical perspective, most of the world’s religions observed asceticism, among them Christianity, Judaism, Islam, Hinduism, Jainism, and Buddhism (Khawaja 8). The research study focuses on the Abrahamic religions including Christianity, Islam and Judaism, on how each of these religions pursued asceticism, both in the past and in the present, in order to achieve religious piety.
