December 15

After the death of Christ the Apostles were troubled and diverged in their thoughts and opinions; later they became steadfast and united. At Pentecost they gathered together, detached themselves from the world, forsook their own desires, renounced all earthly comfort and happiness, sacrificed body and soul to their Beloved, left their homes, took leave of all their cares and belongings, and even forgot their own existence. Then was divine assistance vouchsafed and the power of the Holy Spirit manifested. The spirituality of Christ triumphed and the love of God took hold. On that day they received divine confirmations, and each departed in a different direction to teach the Cause of God and unloosed his tongue to set forth the proofs and testimonies.
