Fratelli Tutti §95
Fratelli Tutti: On Fraternity and Social Friendship
95 Love also impels us towards universal communion. No one can mature or find fulfilment by withdrawing from others. By its very nature, love calls for growth in openness and the ability to accept others as part of a continuing adventure that makes every periphery converge in a greater sense of mutual belonging. As Jesus told us: “You are all brothers” ( Mt 23:8).
