"You must love the Lord your God with all your heart." (Matthew 22:37) Single is a way of love, life, and service. Singleism is an ancient religious practice and people want to sacrifice their lives by participating in religious order to fulfill higher powers. Despite the big controversy in today's religious world, singles are ranked high in many pastors' lives. Many people associate purity and singularity, but the concept is not the same.
One explanation about the origin of compulsion singleism is that it is based on the work of Sao Paulo, who wrote the advantages of singularism and allowed a person to serve the Lord. Celibacy was promoted by early Christian theologians like St. Augustine and Origen of Hippo. Another possible explanation about the origin of compulsion singleism is centered around more practical reasons that "it is necessary to avoid claims of priests' descendants regarding ownership of the church." It is still a Canon's law (and usually the criteria of a particular religious order, especially the criteria of the Franciscan society), the pastor can not possess that land and therefore transfer it to a legitimate or illegal child You can not. The land belongs to the church and the local parish, which is managed by the local parish (usually bishop), is usually the only company of course. Catholic church and various Protestant communities have different views on singleism
All major world religions have for some reason integrated the single discipline concept, marriage and abandonment of sexuality vows, and the Catholic and Protestant churches are no exception. In Catholic church, singleism is a duty of a pastor. It is seen as a symbol of the inseparable succession of Christ. The Protestant church refused the pastor to take on this obligation. Martin Luther wanted the abolition of it as early as 1520. He made a decisive personal contribution to this in 1525: a former monk married a former nun, Catherine von Bola. Luther did not know whether it should be married at the beginning or not, and finally decided that "his marriage pleases the father, brings benefit to the pope, makes the angel laugh, making the devil cry."
