<p>14:22<i> Therefore tongues are for a sign, not to them that believe but to the unbelieving; but prophesying is for a sign, not to the unbelieving but to those that believe</i>- Speaking in foreign languages was to be used for preaching to the unbelieving. The only time speaking in unintelligible language was envisaged, as explained in :21, it was a sign of condemnation to an unbelieving Israel. By doing this to each other, they were thereby proclaiming themselves to be unbelievers. But despite the logic of that position, Paul refuses to condemn the Corinthians and feels and writes towards them as if they are believers. We too may perceive that the logical position required by the behaviour of some 'believers' is that they in fact have lost faith. But all the same, it is not for us to condemn them. There is no example of Paul deciding to block disfellowship a whole group of baptized believers because of their moral or doctrinal errors.&nbsp;&nbsp;</p>
