41. What did the Holy Spirit accomplish in John the Baptist?
The Spirit filled John the Baptist, who was the last prophet of the Old Testament. Under his inspiration John was sent to "prepare for the Lord a people well disposed" (Luke 1:17). He was to proclaim the coming of Christ, the Son of God, upon whom he saw the Spirit descend and remain, the one who "baptized with the Spirit" (John 1:33).

140. What is the work of the Spirit in Mary?
The Holy Spirit brought fulfillment in Mary all the waiting and the preparation of the Old Testament for the coming of Christ. In a singular way he filled her with grace and made her virginity fruitful so that she could give birth to the Son of God made flesh. He made her the Mother of the "whole Christ", that is, of Jesus the Head and of the Church his body. Mary was present with the twelve on the day of Pentecost when the Holy Spirit inaugurated the "last days" with the manifestation of the Church.
