OMG, There is some guff being spouted on this thread. Did Jesus teach you to leave your guests alone? And it's a mortal sin to miss Church for anything other than hospitalisation or death! 
Getting back into the real world..............
If there IS such a Church that chastises you for missing some Sundays, I would not want to live in that community, or attend that Church where it's a 'mortal sin' to miss a Sunday attendance now and again! I may go if I have guests, I may not. Depends if I feel like it or not. If we have been drinking the night before and I have a hangover, then no I won't go.
I think there is some kind of bizarre assumption (from some) that the more you go to Church, the better a person you are. Couldn't be further from the truth. I know some people who never go to Church, or only go 6-8 times a year, who are the loveliest people I know, and also some people who attend weekly, who are utterly vile; judgemental, scornful, questioning people who 'only' go once or twice a month, and think everything is a sin.
A vicar once told me 'you can be whatever type of Christian you want to be, and coming to Church every single week doesn't make a person better than those who attend once a month.'
There are many ways to be a good Christian, but going to Church every single week doesn't make you a better Christian, or a better person.
