FOOTNOTE 192 29 [April 1937]. The Lord gave me to know about the disputes  that were going on in the Vatican concerning this Feast. The dignitary Pacelli did much work on this†† (Diary 1110) ††††
 We do not know to what talks the vision refers. But we know that Father Sopocko sent a memorial on The Divine Mercy to the participants of the First Plenary Synod, which was held at Czestochowa on August 26-27, 1936. The Pope's legate, Msgr. Marmaggi presided at the Synod. He probably mentioned the matter of promulgating a Feast of The Divine Mercy in his report of the Synod to the Holy See. That may have caused the disputes. We have reason to suppose that the report drew the interest of Eugene Cardinal Pacelli, Secretary of State (and later, Pope Pius XII). But it is difficult to say what the work could have been. The fact that the notification banning the devotion was not issued by the Holy Office until after his death (November 28, 1958) suggests that Cardinal Pacelli's attitude toward the devotion to The Divine Mercy was a favorable one.
