Pentecost ist the birthday of the Church! This was when Jesus sent the Holy Spirit down to his apostles and disciples. The Holy Spirit is the third person of the Holy Trinity: Father, Son and Holy Spirit. Pentecost was yesterday on Sunday.
O Lord Jesus Christ, Who, before ascending into heaven, didst promise to send the Holy Ghost to finish Thy work in the souls of Thy Apostles and Disciples, deign to grant the same Holy Spirit to me, that He may perfect in my soul the work of Thy grace and Thy love.
Grant me the Spirit of Wisdom that I may despise the perishable things of this world and aspire only after the things that are eternal,
the Spirit of Understanding to enlighten my mind with the light of Thy divine truth,
the Spirit of Counsel that I may ever choose the surest way of pleasing God and gaining Heaven,
the Spirit of Fortitude that I may bear my cross with Thee, and that I may overcome with courage all the obstacles that oppose my salvation,
the Spirit of Knowledge that I may know God and know myself and grow perfect in the science of the Saints,
the Spirit of Piety that I may find the service of God sweet and amiable,
the Spirit of Fear that I may be filled with a loving reverence towards God, and may dread in any way to displease Him.
Mark me, dear Lord, with the sign of Thy true disciples and animate me in all things with Thy Spirit. Amen.
