We don't have to explain. Paul states they would be "done away" when the "perfect has come." They had already vanished before Paul wrote "Romans."
Here we have a church with no miraculous, spiritual gifts. Did he not say that this was the reason he wanted to visit this church? To impart UNTO YOU SOME spiritual gifts" How? by the laying on of his hands.
(Romans 1:11). These "miraculous" spiritual gifts are not even listed in Galatians 5:22-26.
Question: Catholicism informs us that Peter was the "first Pope of Rome." Why had not Peter laid hands on anyone in the Roman church to "impart SOME spiritual gifts" if this was the paramount "POWER" of the church?
Did Paul not say that the "Gospel was the POWER of God unto salvation to everyone that believes"? (1:16). Could it be this was the reason Jesus said "Go teach and MAKE disciples."? "Make" being the action verb.
Now, let's get back to who transferred these "spiritual gifts" to men in building the super structure of His church. When one strays too far from the book of Acts expect to run into "Mysticism."
Ever wonder why Simon of Samaria (Acts 8) "a believer," did not enquire of Philip for the "gift of the Holy Spirit"? Simon saw something that today's charismatic movement has not! He tells us why in verse 18. You should "hi-lite" this verse for future reference when "making disciples."
"And when Simon saw that through laying on of APOSTLES' HANDS ("Peter and John 'SENT' by the church in Jerusalem vs 14-17) the Holy Spirit was GIVEN."
How was the Holy Spirit GIVEN? It took the hands of an Apostle to impart gifts.
The apostles are GONE. Anyone claiming this "POWER" today is a phony and should receive the same rebuke Peter laid on Simon for "offering the apostles MONEY for this "POWER." Wonder how man churches have been built on this premise? How man souls lost because phony men have claimed this power?
