Is Missing Church a SIN?

I heard a pastor here recently say that missing church is a sin.

I am wondering about all this justified means to accomplish the desired end business.

It seems that folks now are putting dire quid pro quo, provisos, circumstances and consequenses on just about anything and everything with the thought that, "If it keeps people praying, going to church, locked into the system, then it doesn't matter what method we use, biblical or not, true or not, accurate or not."

So, is missing church a sin?
