“Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us,
Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection.” — Acts 1:21-22
is talking about replacing a DISCIPLE . . .
Personally, I think they erred and that Christ had chosen Paul. However, even then, they were already getting legalistic.
If you wish to ignore all Holy Spirit did through Paul IN ADDITION to Christ’s special commissioning of him and his conditioning in the wilderness . . . help yourself.
Doesn’t make sense to me.
