In 1928, at his mother's instigation, he began further studies at the school of the Passionsts in Przasnysz.

He entered the Passionist Congregation as a novice in 1933, taking the name Bernard of the Mother of Fair Love, and one year later made his first vows.

He was sent to Rome in 1936 to study theology at the headquarters of the Passionist Congregation and made his perpetual profession of vows one year later.

In 1945, the Passionist house was turned into a hospital and Bernard worked as nurse and cook.

Due to his work among the sick he contracted typhus and died in July 1945 at the age of 30.
