From Vatican News:
In his continuing catechesis on the Acts of the Apostles in the Paul VI hall on Wednesday, Pope Francis spoke of the solidarity between Christians and how it is essential in building up God’s family. This fraternity he said, “is nourished by receiving the sacrament of Christ’s Body and Blood.”
The Pope underlined that there is a “dynamism of solidarity that builds the Church as the family of God, where the experience of koinonia is central.” He explained that in the Church of its origins, “this koinonia, this community, refers first of all to participation in the Body and Blood of Christ.” For this reason, the Pontiff said, “when we receive communion we declare “we communicate”, we enter into communion with Jesus and from this communion with Jesus we arrive at communion with our brothers and sisters.”
