Early Life and Monastic Career
Pitirim was born in Vyazma and given the name Procopius at baptism. According to his life, he was a devout child who learned to read and write early, attended the church services, and formed the habit of prayer, taking particular delight in the writings of the holy Fathers and the Lives of the Saints. He was also endowed with artistic talent, occupying himself with the painting of icons and with church singing.
At about the age of twenty-one he entered the Monastery of Saint John the Baptist at Vyazma, a community noted for its strict rule, where he received monastic tonsure and the name Pitirim. His ascetic manner of life won him the respect of the brethren, who chose him igumen, and in 1684 he was raised to the dignity of archimandrite.
