Bede the Venerable
Catena Aurea · Lukasevangelium 11
And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask an egg, will he offer him a scorpion? If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?
Or, he calls the lovers of the world evil, who give those things which they judge good according to their sense, which are also good in their nature, and are useful to aid imperfect life. Hence he adds, Know how to give good gifts to your children. The Apostles even, who by the merit of their election had exceeded the goodness of mankind in general, are said to be evil in comparison with Divine goodness, since nothing is of itself good but God alone. But that which is added, How much more shall your heavenly Father give the Holy Spirit to them that ask him, for which Matthew has written, will give good things to them that ask him, shews that the Holy Spirit is the fulness of God’s gifts, since all the advantages which are received from the grace of God’s gifts flow from that source.
