Paul wrote to Timothy:
2Ti_1:6 Therefore I remind you to stir up the gift of God which is in you through the laying on of my hands.
So we know he practiced laying on of hands to give God's spirit. And he says twice in other letters:
1Co 4:16 Therefore I urge you, imitate me.
1Co 11:1 Imitate me, just as I also imitate Christ.
1Co 11:2 Now I praise you, brethren, that you remember me in all things and keep the traditions just as I delivered them to you.
Since it was the practice of Paul and Paul was a prominent Christian who established many Christian churches...and since Paul was visited by and learned from Christ...I would say we're on pretty firm ground by taking his word and example on it.
Good point!!
1 Corinthians 1:17
For Christ did not send me to baptize, but to preach the gospel—not with wisdom and eloquence, lest the cross of Christ be emptied of its power.
