That forgiven thief was not a part of the Church Age. He was one of the last Christ-believers saved under the Law, and went to Hell--the Paradise part, where Jesus' soul went to preach to him, and in a few hours transited the whole Paradise portion to be separated from Hell and joined to Heaven.
This thief was not a candidate for baptism, and will not be a member of the Bride.
At the wedding, he will be a friend of the Bride, IIRC.
LOL....Seriously ?
