Pope Francis appointed Saturday four cardinals as presidents delegate to the synod on youth, which will meet at the Vatican in October.

His July 14 appointments were Cardinal Louis Raphael I Sako, Chaldean Patriarch of Babylon; Cardinal Désiré Tsarahazana of Toamasina; Cardinal Charles Maung Bo of Yangon; and Cardinal John Ribat of Port Moresby.

Each were appointed cardinal by Pope Francis.

The presidents delegate will take turns presiding over the synod on the pope's behalf. They are to guide the synod's work, delgate special tasks, and sign the synod's documents.

The Oct. 3-28 Synod of Bishops on Young People, the Faith and the Discernment of Vocation will address questions of sexuality and gender, the role of women, and the desire for a Church which knows how to listen.

The synod's instrumentum laboris was issued last month, and key issues highlighted in it include increasing cultural instability and conflict, and that many young people, both inside and outside of the Church, are divided when it comes to topics related to sexuality, the role of women, and the need to be more welcoming to members of the LGBT community.
