BD: Acts 1:8, But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. The great commission has universally been interpreted to mean it is incumbent on all believers to make disciples
That's not what the NT says anywhere. I have already pointed out that the Great Commission was given to the 11 (remaining) Apostles, not all of whom believed.
The book of Acts to which you reference tells us
In fact, the entire Act 1:1-8 is a dialogue between Christ and his Apostles only, and that, of course, includes verse 1:8 which you present as evidence to the contrary!
Where Christ is quoted as saying "You shall be witness..." it refers to the Apostles and no one else because no one else was there! This is perfectly consistent with 1 Cor 12:28-29
All are not apostles, are they? All are not prophets, are they? All are not teachers, are they? All are not workers of miracles, are they?
and Eph 4:11
So, the only thing that is phoney-baloney is the "universal" interpretation that He commissioned all the believers. Rather, He gave the authority to choose others, consecrate and bless (to bind and losen) only to them His 11 remaining disciples.
“Where did you get all believers from?
“Acts 1:8, But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
Now let’s see, on whom did the Holy Spirit fall, Acts 2:18, “ And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:” Sounds like it was for all to be witnesses. It was the the christians that were dispersed because of the Stephen persecution that carried the Gospel to Judea, Samaria and the uttermost parts of the earth.
