In May 2019, Pope Francis stated that Irinej had helped in the reflection in the Catholic Church about the canonization of World War II Croatian Cardinal Aloysius Stepinac, which the Serbian Orthodox Church opposes due to his role in the Nazi-allied Independent State of Croatia (NDH). "I sought advice and I saw that I need to seek help from Irinej. He is a great patriarch. Irinej helped, we created a joint historic commission, and we cooperated," said the Pope. "The truth is both mine and Irinej's only interest."
