We are in the ecumenical time of creation; the annual celebration that symbolically begins on September 1, World Day of Prayer for the Care of Creation, and ends on October 4, the Celebration of St. Francis of Assisi, patron saint of ecology.

The theme for 2021 is "A Home for All? Renewing God's Oikos," the house of God; this is the meaning of the Greek term Oikos, as an integral network of relationships that support the well-being of the Church.

Creation is everyone's home, threatened, however, in recent years by climate change, environmental disasters, and threats to the world's most vulnerable populations. And it is precisely on these issues that Pope Francis, in his message addressed to all the faithful, calls for "decisive and urgent action to transform this crisis into opportunity," emphasizing how the cry of the Earth and the poor is becoming increasingly alarming.

On the occasion of the sixth year of publication of the encyclical "Laudato Si'", Pope Francis, together with the Dicastery for the Service of Integral Human Development, invites people to take part in prayer, sustainability and mobilization to "renew faith in God the Creator and unite in a special way in prayer and action for the care of our common home."

The symbol of Creation Time chosen for this year is Abraham's tent, a symbol of the ecumenical call to radical hospitality, to safeguard every creature on our Earth as a "home for all." Just as Abraham and Sarah opened their tent to three strangers, who later revealed themselves to be angels of God (Genesis 18), so the faithful of the world are invited to care for creation and to be hospitable.

The invitation is to welcome this Season of Creation to reflect and at the same time act towards an integral ecological transition, as indicated in Laudato Si', to recover the close connection with the Earth, God's creation from which everything comes.
