When the different theological, liturgical, spiritual and canonical traditions are “genuinely rooted in the apostolic tradition,” he noted, they are an “asset, not a threat” to the unity of the Church.
If we let ourselves be guided by the Holy Spirit, he said, the “richness, the variety, diversity” do not become a source of conflict, but are instead a point of enrichment.In 2013, Pope Francis made a beautiful and very moving speech about "unity grounded in diversity." You can read his speech here. Christ created a universal Church that embraces the diversity of the gifts of the Holy Spirit. It was never the liturgy that kept us Catholic. It was our baptism and our union with the Pope and Church hierarchy that made us Catholic.
There are people in the Catholic Church who are unable to receive Holy Communion, but they are STILL Catholics. Baptized children are unable to receive the Body of Christ until they reach a certain age. There are infants who died and never received the Eucharist, but these children are Catholics and one with Christ and His Church through their baptism. There are some Catholics unable to receive the Body of Christ, but they are still Catholics. It is our baptism and our union with the Pope and Church hierarchy that make us Catholics. We entered into God's family through our baptism, and we became one with Christ through the Eucharist as we receive His Body and Blood.
