Celibacy is defined as the lifestyle of someone who is, and is striving to remain, unmarried all his/her life. It is also used to describe a state of life where one chooses to abstain from all sexual activities (also known as "continence"). Often, it is incorrectly used to refer to a mixed, an involuntary, or even temporary abstinence from sexual relations – celibacy is by definition a freely chosen state of being unmarried and practicing sexual abstinence.
The English word celibacy derives from the Latin caelebs, meaning "unmarried". This word derives from two Proto-Indo-European stems, *kaiwelo- "alone" and *lib(h)s- "living".
Celibacy termed as Brahmacharya in Vedic scripture is the fourth of the yamas and the word literally translated means "dedicated to the Divinity of Life". The word is often used in yogic practice to refer to celibacy or denying pleasure, but this is only a small part of what Brahmacharya represents. The purpose of practicing Brahmacharya is to keep you focused on your purpose in life, the things that instill a feeling of peace and contentment. In Hinduism, celibacy is usually associated with the sadhus ("holy men"), ascetics who withdraw from worldly ties.[2]
The rule of celibacy in the Buddhist religion whether Mahayana or Theravada has a long history, it was advocated as an ideal rule of life for all monks and nuns by Gautama Buddha, however in Japan it is not strictly followed due to historical political developments in Japan. Siddhartha Gautama, later known as the Buddha, is very well known for his renunciation of his wife, Princess Yasodharā, and child, Rahula. In order to pursue an ascetic life, he needed to renounce aspects of the impermanent world, including his wife and child.
Celibacy is viewed differently by various Christian denominations. It includes clerical celibacy, voluntary lay celibacy, and celibacy outside of marriage.
Celibacy as a vocation may be independent from religious vows. Traditionally though, most celibate persons have been religious and monastics (brothers/monks and sisters/nuns). In all pre-Protestant - Catholic, Orthodox and Oriental Orthodox - traditions, bishops are required to be celibate. In the Eastern Christian traditions, priests and deacons are allowed to be married, yet have to remain celibate if they are unmarried at the time of ordination.
A few minor Christian sects even advocated celibacy as a better way of life for everyone. These groups included the following: the Shakers, the Harmony Society, and the Ephrata Cloister.
The view of the Roman Catholic Church remain that celibacy is more than a reflection of life in Heaven, a source of detachment from the material world, which aids in one's relationship with God. Celibacy is designed to "consecrate themselves with undivided heart to the Lord and to "the affairs of the Lord, they give themselves entirely to God and to men. It is a sign of this new life to the service of which the Church's minister is consecrated; accepted with a joyous heart celibacy radiantly proclaims the Reign of God." Catholic priests are called to be espoused to the Church itself, and espoused to God, without overwhelming, exclusive commitments interfering with the relationship. Catholics understand celibacy as the calling of some, but not of all. Celibacy was generally required of the bishop in the early church. A married man could be made bishop, but after his ordination, he was generally required to live apart from his wife. Celibacy was also practiced by many presbyters, especially in the West, but was not universally required. It became obligatory for all priests in the west in the 12th century at the First Lateran Council (1123), Second Lateran Council (1139), and the Council of Trent (1545–64).
