The monk spent thirty years at the Protection Monastery, where he was igumen, Elder, and Father-confessor. At fifty-one years of age he fell grievously ill, gave up his position as igumen and was tonsured into the Great Schema. After recovering his health on April 23, 1444 (the Feast of the holy Great Martyr George the Victory-Bearer), he left the monastery and settled with one monk on the left bank of the River Protva, where it meets the River Isterma. Soon brethren began to gather to him at this new place, and the number of the monks quickly grew. A new stone church was built in place of the former wooden one, in honor of the Nativity of the Most Holy Theotokos.

The finest iconographers of those times, Dionysius, Metrophanes, and their assistants were invited to adorn the church with icons and frescoes. St Paphnutius was an example to the brethren, leading a strict life. His cell was the poorest of all, and he chose the worst morsels of food. On Mondays and Fridays he ate nothing at all, and on Wednesdays he only ate dry food. He did the most difficult tasks himself. He chopped and carried fire wood, dug and cultivated the garden, yet he was always the first to arrive for church services.

St Paphnutius earned the deep respect and love not only of the brethren of his own monastery, but also of other monasteries. Through the providence of God a twenty-year-old youth, John Sanin was guided to the monastery. After testing him for a time, Paphnutius tonsured him into monasticism with the name Joseph. Later on St Joseph of Volokolamsk defended the purity of the Orthodox Faith and entered into struggle against the heresy of the Judaizers, condemned at the Council of 1504. St Paphnutius blessed the young man in his endeavors.

A week before his death, the saint foretold his end. After he had prayed and blessed the brethren, he fell asleep in the Lord on May 1, 1477. St Paphnutius was a disciple of St Sergius of Radonezh.
