But why did Paul need to impart spiritual gifts? They already had them. But they like Phillip could not pass them on. Only an Apostle could do this.
Paul imparted his gift he was the office of Apostle. which is a gift to the body of Christ for equipping as the word of God says in 1cor 12
and Ephesians 4:11-12 says. Rom 12:6-8 tells us teaching is a gift. it is not all the Spiritual gifts only in context to the :
pneumatikos AND the charisma
THERE ARE ALSO :
katartismos = equipping gifts
Eph 4:11-12
And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, 12 for the equipping of the saints for the work of service, to the building up of the body of Christ
When Paul said in Rom 1:11
For I long to see you, that I may impart to you some spiritual gift, so that you may be established NKJV
it was not by laying on of hands because of the context of the word " impart spiritual gift " means also
a favour with which one receives without any merit of his own
the gift of faith, knowledge, holiness, virtue
to make the firm in the faith or as it says in verse 11 established.
