Christ's Desire for Unity

Christ, offended, said in a message: "My Kingdom on earth is My Church and the Eucharist is the Life of My Church, this Church I Myself have given you. I had left you with one Church but hardly had I left, just barely had I turned back to go to the Father, than you reduced My House to a desolation! You leveled it to the ground! And My flock is straying left and right. For how long am I to drink the Cup of your division? Cup of affliction and devastation!

Love is the root and the foundation of unity. If the Church is not yet living in full communion it is because everything that is expressed or discussed and explained is done without love, it's sterile. This division is directed against Christ. All who call themselves Christians and abide divided have broken the Commandment of Jesus Christ who said: "Love one another." Let's face it, the Christians who do not love and have only lived in self glory will never reconcile because they have not yet grown fully into Christ.

  ...I am asking the officials of the Church to stop their quarrels between themselves for the sake of Christ's Love and their insincerity and indifference towards unity and permit the Holy Spirit to guide them, by listen to the groaning of the Spirit that asks, commands us to unite around one Altar, sharing one Cup and one Bread, and together proclaiming in one voice that there is one Lord, one faith, one baptism and one God who is Father of all, over all, through all and within all.
