And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins. (1 Peter 4:8 KJV)
Let's face it, we all have our shortcomings...areas in which we sin, whether by omission or by comission. In the church there are all kids of different Christians. Some with rough personalities, and others who are more refined. All too often I have seen those who should have been more mature by reason of how long they have been a Christian, become greatly offended with another in the church who might not be quite as refined as they. It has gotten so ugly at times the pastor has gotten dragged into to referee. Sometimes it all results in a church split as each side tries to gather followers to their side. These things ought not to be in the church!
We are commanded to have charity among ourselves and in so doing a multitude of sins can be covered over. So what if so and so said something that offended you? You have three choices. You can either put the best construction on it and let it go, talk to them privately, or you can nurse your wounds and complain to others, starting a gossip chain through the church. What it comes down to is this: We are each responsible before God for our actions. When someone offends me, what do I do with it? Are the actions I'm thinking of taking pleasing to God or not? Am I assassinating the other person's character by what I am doing and saying? Having charity with one another helps to smooth over these areas of friction and helps us in the church to be at peace with one another.
