Barnabas and Paul were chosen by the Holy Spirit. The Faith the early Church had in the promptings of the Holy Spirit is certainly lacking  throughout the rest of History as known by me. I can see in a few Saints the absolute belief that the first Christians grasped so eagerly. The ordination of Barnabas and Saul is prepared for by fasting and prayer and then they are sent off. The Apostles were told to follow the Lord but their disciples are "sent off", emitted on their mission to spread Christ's good news to all the world.

Dear Lord the acceptance of your Holy Spirit needs a mission to fulfil it. What about me? help me in my weakness.

Jesus' plain and public speaking about his nature and his relationship to the Father is quite explicit. He is identical with the Father and his presence and words are from and the same as the Father's. This Light that is brought into the world is the same as blinded St Paul. We too are blinded not directly by the Light but by the problems caused by our own egos which want to create  versions of  the Truth to bolster our own  selves. Christ's words need to be interpreted to be understood but in no way changed. In this we must trust the Holy Spirit and beseech him to support those with a vocation to the priesthood, God send us holy priests.

Dear Lord you call us but we do not answer. Let the Church of Peter be purged of the nonsense that is obscuring our way to you. Let your mother's "Let it Be" be our guiding light. Holy Mary Mother of God pray for us sinners now and at the hour of our death. Amen!!!
