Looking for candidates for confreres and a place for the seat of the community, the monk Stanisław Papczyński decided to join several hermits living in the Korabiewska Forest near Skierniewice. At the will of the inspector, Bishop Jacek Święcicki, he became their superior. He made an effort to organize the life of this community on the basis of the "Norma vitae" rule he had prepared and the bishop's post-visitation recommendations.

In the rule he prepared he wrote: "I believe in everything that the Holy Roman Church believes ... and, above all, I confess that the Most Holy Mother of God, Mary, was conceived without original sin," although at that time this truth was not yet solemnly defined as a dogma faith. The second important point in the draft rule was related to the mystical experiences of the founder of the Congregation of Marian Fathers regarding intercession for the dead. He recommended to his brothers: "Pray, brothers, for the souls in Purgatory, because they suffer unbearably torment." He knew that many soldiers die without being reconciled to God. He was also aware of the fact that large numbers of people died as a result of frequent epidemics. He proclaimed that it is a Christian's duty to help them with prayer. He also assigned other apostolic tasks to his confreres. He wanted them to support parish priests in hearing confessions and to preach among the most religiously neglected groups.

On October 24, 1673, in which Bishop Jacek Święcicki approved the existence of a young community in the Korabiewska Forest based on the "Rule of Life" and his post-visit recommendations. A very important role in the life of the developing community was played by Bishop Stefan Wierzbowski, who in 1677 entrusted it with the Church of the Lord's Supper with an adjacent monastery in Góra near Warsaw. Two years later, the institute of Father Papczyński was established by the same bishop with diocesan law. It was then that Father Papczyński set off on foot to Rome to also obtain papal approval for his congregation.
