Let's look at the passage a slightly different way.......
Quote
1Co 13:8-13 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away. When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity. (KJV)
First problem for your friend is that the passage uses two different time frames, not one. Making perfect mean Jesus or heaven requires that all these gifts will end at the same time. However, the text disagrees with this.
One serious dilemma your friends creates is an open canon. If prophecy has not ceased, scripture may still be open and Sola Scriptura is false. To be a Christian, you have to uphold a closed, completed canon.......which means that prophecy has ceased.
One other serious problem your friend will have is historical support.......he has none. For 1800 years, this gift was considered ceased. Even some of the early church writers noted this.
