出版的使徒必須為所有離開教會的人帶來光明,為他們回歸教會鋪平道路。以兄弟之愛,帶著好牧人的良善之心,去尋找迷失的羊,把牠扛在肩上,帶回羊舍。
To all those in error the apostle with the editions must bring light, pave the way for their return to the Catholic Church, with fraternal charity, with the goodness of the Good Shepherd who goes in search of the lost sheep, takes it on his shoulders and brings it back to the sheepfold (UPS IV, 119).
