The book, entitled "...da svijet uzvjeruje" ("...so the world may believe", unofficial translation), is a collection of Lingua's sermons delivered on different occasions during his term in Croatia.
Lingua said it was motivated by his encounters with the faithful in Croatia, who often told him that they still remember his sermons and spoke about their effect on them.
Those were not just compliments, one could see a wish to share the personal experience of the encounter with the word of God, Lingua said, adding that he had been surprised by numerous invitations to give sermons in different parts of Croatia, which, he said, had helped him become better acquainted with the beauty of the religious devotion of the Croat people and the way they practice their faith.
The first sermon in the book is one delivered at the start of Lingua's mission in Croatia, in October 2019, and the last is from March 2024, delivered on the occasion of the 11th anniversary of the election of Pope Francis.
