"O my dearly beloved brethren!" exclaims St. Gregory the Great, "think what a dignity it is to have God abiding as a guest in our heart! Surely, if some rich man or some powerful friend were to come into our house, we would hasten to have our whole house cleaned, lest, perchance, when he came in he should see anything to displease his eye. So let him that would make his mind an abode for God cleanse it from all the filth of works of iniquity." {266} "And they were persevering with one mind in prayer." Our prayer must be persevering if we would gain that which we desire. This is what our Lord meant when he said that we ought always to pray and not to faint. Unless we persevere in prayer we shall without doubt faint by the way in the journey of life. And let us do as the Apostles did, join our prayers to those of Mary, the Mother of Jesus, and we shall have a sure hope of obtaining what is most needful for us. Then, as the Holy Ghost once descended upon her, and wrought within her the Incarnation, so also will he come into our hearts, and make them the abode of the Holy Trinity. Then, if we listen to his blessed voice within us, we shall grow in grace and in the knowledge of our Lord and Saviour Jesus Christ, for the Holy Ghost will teach us all things, according to the promise. ------------------- {267} _Feast of Pentecost, or Whit-Sunday._ Epistle. _Acts ii. _1-11. When the days of the Pentecost were accomplished, they were all together in the same place: and suddenly there came a sound from heaven, as of a mighty wind coming, and it filled the whole house where they were sitting. And there appeared to them cloven tongues as it were of fire, and it sat upon every one of them, And they were all filled with the Holy Ghost, and they began to speak with divers tongues, according as the Holy Ghost gave them to speak. Now there were dwelling at Jerusalem Jews, devout men out of every nation under heaven. And when this voice was made, the multitude came together, and were confounded in mind, because that every one heard them speak in his own tongue. And they were all amazed and wondered, saying: Behold, are not all these who speak Galileans? And how have we every one heard our own tongue wherein we were born? Parthians, and Medes, and Elamites, and inhabitants of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphilia, Egypt and the parts of Lybia about Cyrene, and strangers of Rome, Jews also, and proselytes, Cretes and Arabians; we have heard them speak in our own tongues the wonderful works of God.
