When one desiring the monastic life enters a monastery, he normally passes through three steps or stages: 1) Probationer (Novice including Riasaphor), 2) Monk of the Lesser Schema (Cross-bearer or Stavrophore), and 3) Monk of the Great Schema (Russian Skhimnik). The Probationer who enters a monastery desires to do so in order to acquit himself worthily in the angelic state, so called because Monks renounce all wordly things, do not marry, do not acquire and hold property, and live as do the Angels in Heaven, glorifying God night and day and striving to do His Will in all things.

It is generally accepted that monasticism began in Egypt towards the end of the Third Century, though its origins may have been older. Indeed, some form of monasticism may have existed almost from the birth of the Church. As the word monastic implies (in Greek monos alone), the Monk was one who went into the desert to live alone with God. (Such were also called hermits (or anchorites), which means solitaries.) The first recorded hermitic Orthodox Christian literature was St. Paul of Thebes ( 341) who lived over sixty years in a cave in the Egyptian desert. But the greatest of these hermits, often called the Father of Monasticism, was St. Anthony the Great ( 356).
