I stole this prayer from JonathanCatholic. Prayers needed, please, for unity.
O Lord Jesus Christ, who, when You were about to suffer, prayed for Your disciples to the end of time that they might all be one, as You are in the Father and the Father in You:
Look down in pity on the manifold divisions among those who profess Your faith, and heal the many wounds which the pride of man and the craft of Satan have inflicted upon Your people.
Break down the walls of separation which divide one part and denomination of Christians from another. Teach all that the See of St Peter, the Holy Church of Rome, is the foundation, centre and instrument of unity.
Open their hearts to the long-forgotten truth that our Holy Father, the Pope, is Your vicar and representative; and that in obeying him in matters of religion they are obeying You, so that, as there is but one holy company in heaven above, so likewise there may be but one communion, confessing and glorifying Your holy Name here below. Amen.- Bl. John Henry Cardinal Newman
