This is the problem when we automatically elevate entertainers to the status of ministers. Many are not. Some ministering may take place, but just because someone has talent which may be used for God's purposes does necessarily mean that they are called to the ministry in the sense that a bishop or evangelist or any levitical office is. All of us, to some degree, are ministers of the gospel and we all have a certain sphere of influence. The question that we have to ask ourselves is weather or not our actions and words reflect that we are who and what we say we are. And as such, we need to be careful not to offend those who are not that strong in the faith. For me, I could care less that Mary Mary went to see Beyonce' perform, but for some young person this could send a confusing message.
