Jesus promised the Holy Spirit:
“If you love me, you will keep my commandments. And I will ask the Father, and He will give you another Advocate to be with you always, the Spirit of truth, which the world cannot accept, because it neither sees nor knows it. But you know it, because it remains with you, and will be in you.” (John 14:15-17)
“I have told you this while I am with you. The Advocate, the Holy Spirit the Father will send in my name will teach you everything and remind you of all that [I] told you.” (John 14:25-26)
The Christian Church was founded on Pentecost, the day the Holy Spirit descended over the apostles. The Acts of the Apostles, Acts, is the fifth book of the New Testament, and covers the founding of the Christian Church, the Early Church, and the spread of the Gospel throughout the Roman Empire.
The Holy Spirit has been the most active and the least known member of the Holy Trinity since the founding of Christianity. He was very powerful in the development of the Early Church and will exert even more power in The Church of the Last Days. The future Pope Peter II will lead this Church centered in the Philippines.
