Pope Leo XIV has issued a new Apostolic Letter urging Christians to recover the unity of faith first expressed at the Council of Nicaea 1,700 years ago.
Released on the 23rd for the feast of Christ the King, In unitate fidei comes just days before the Pope begins his first foreign journey, a highly symbolic visit to Türkiye, where he will mark the anniversary at the site of the ancient council.
The document, running to twelve sections, takes the Nicene Creed as the starting point for a renewed call to communion among Christians.
