On the advice of his mentor Cardinal Sapieha, Karol Wojtyla (future Pope John Paul II) and a fellow Polish priest studying in Italy, Stanislaw Starowieyski, travelled to France and Belgium to acquaint themselves with the worker-priest movement. Wojtyla, who had also performed hard labor during his time as a seminarian, reportedly admired the worker-priests. On his return in 1947, Wojtyla wrote a piece on the worker-priests for the "Tygodnik Powszechny". Wojtyla wrote: "Father Loew came to the conclusion that the white habit by itself does not say anything any more today."
