Christian life is a battle each person must fight against the temptation to be self-sufficient and against a paganism disguised as sacredness, Pope Francis said in an introduction to a small book distributed to participants at the synod on synodality.

The formation of seminarians, the Catholic Church as a welcoming home for all, migration and ecumenism arose as common themes of discussion among participants of the assembly of the Synod of Bishops Oct. 6, the Vatican said.

For the duration of the assembly Oct. 4-29 all the heads of Vatican dicasteries and hundreds of cardinals, archbishops, bishops, religious superiors, professors, students and parents were scheduled to be away from their homes and their desks.

The 364 members of the assembly of the Synod of Bishops and the 85 experts, facilitators and ecumenical delegates accompanying them began their work in earnest Oct. 5, meeting, sharing and praying in small groups.

Pope Francis opened the work of the assembly of the Synod of Bishops asking members to meditate on ancient theological texts about the Holy Spirit, have the courage to be honest about their disagreements and focus much more on listening than on sharing their opinions.

As the Synod on Synodality opened Oct. 4 in Rome, among the most closely watched topics under discussion is the question of whether the Catholic Church can or will extend the permanent diaconate — restored after the Second Vatican Council — to women.

After warning the world against ignoring the cries of the earth and the poor with his 2015 encyclical, “Laudato Si’, On Care for Our Common Home,” Pope Francis intensified his critique with “Laudate Deum” (“Praise God”), warning against the selfish obsession with human power and the “irresponsible derision” of the reality of climate change.

Members of the assembly of the Synod of Bishops are not gathered in Rome to implement a “plan of reformation” but to walk together as a church that discerns God’s will for the present moment, Pope Francis said at the assembly’s opening Mass.

Four days after creating new cardinals, Pope Francis gave an extra job or two to the 18 prelates who are under the retirement age of 80.

Competing notions of authority and giving certain Christian truths preeminence over others can not only derail the assembly of the Synod of Bishops but, worse, cripple the church’s ability to share Christ with the world, Dominican Father Timothy Radcliffe told synod members.
