No, suits should not be a requirement for church. But, yet the argument has been raised. This topic should not even be an issue. Really it should be left up to the man and whether or not he feels comfortable in a suit. I will admit that a man should look presentable for church but he can look presentable in a pair of KhakiS or really nice pair of jeans. We should never become so focused on issue that we become so inward and miss the point that it is about a relationship and not dress. When we start to make something a requirement we are really imposing our convictions on to others. When we begin to follow another mans ways or convictions we are simply conforming to their ways. I understand that we need to dress nice for God but it should never become a requirement or obligation.
