The close friendship of Pope Francis and Ecumenical Patriarch Bartholomew as the leaders of the two largest Christian communities, as well as their joint efforts to promote ecological awareness across the planet, was the focus of Halki Summit V held in Istanbul, organized by the Ecumenical Patriarchate (June 8-11, 2022)

Sustaining the Future of our Planet Together contains the addresses of the speakers, inspired by the conviction of Patriarch Bartholomew to "Remember and reinforce connections between ourselves and God's creation, between our faith and our action, between our theology and our spirituality, between what we say and what we do, between science and religion, between our beliefs and every discipline, between our sacramental communion and our social connections, between our generation and the generations to come, just as between heaven and earth, between our two churches, but also with other churches and other faith communities."
