Fifty days after the death and resurrection of Jesus, the Catholic Church celebrates Pentecost. On this feast day that concludes the Easter season, Catholics celebrate the beginning of the Church.
The word Pentecost is derived from the Greek word “pentecoste” which means fiftieth.
In Christian tradition, the faithful celebrate at Pentecost the coming of the Holy Spirit to Mary, the apostles, and the first followers of Jesus as they were gathered in the Upper Room. It was said that a “strong, driving” wind filled the room, and tongues of fire rested on their heads, which allowed them to speak in different foreign languages enabling them to understand each other. The phenomenon was strange that some people dismissed the Christians as drunk. However, Peter noted that it was only morning at that time and the Holy Spirit caused the phenomenon. Right after this, Peter, who was inspired by the Holy Spirit gave his first homily to the Jews and many non-believers. And in opening the scriptures, he has shown how Prophet Joel prophesied these events and the coming of the Holy Spirit. (cf. Acts 2) Thus, the day of the Pentecost was considered the birth of the Church with Peter, the first Pope, giving his first preaching and converting thousands of new believers.
Necessary to fulfill their commission, the Holy Spirit has given gifts and fruits to the apostles namely:
