Can I assume everyone who is here at the moment is not a Christian because you are not in church?

I am a christian and I'm not in church. 

No I am a Christian but not currently a member of any church. 

the only church I’m interested in is the church of the eternal slumber 

otherwise known as me sleeping until noon

?  No.

You cannot.  Church goes on when it goes on.  Some go on Saturday night. 

Nailed it!

My home is like a church because everybody is asleep - the only thing missing is a pointy roof.

You are correct about me.
So dont let it get you down, 2 out of 8 aint  bad. but how about yourself, or are you sitting in the pew posting questions on AM or are you godless too?

You might assume they may be aware that Sunday is NOT the Sabbath.

Some Christians are Seventh Day Adventists, Seventh Day Baptists or Worldwide Church of God so they would have gone to church yesterday morning.  Some other churches have a service on a different night of the week in addition to their Sunday morning service for people who might still want to go to church but don't want to get up early on Sunday morning but you're right about me.  I'm not a Christian.  I'm not anything else either so my Sunday mornings are spent doing farm things and doing mom things with an occasional peek to see what's on the internet.

The Word of God is in me while sitting here on a Sunday with the church within me.   I did the same on the biblical Sabbath.

I was not here this morning because I was with my mom at a Catholic mass. :)

Just got home and now it's time to go grocery shopping...

I remember being given a palm branch when I was very young. I was in Sunday school. 

Well now no making assumptions...I aint saying either way... but do remember that some of us are in entirely different time zones :P

Yes....we are all sane and sensible in my extended family..... Nonsense was banned  long before  I was born.....

You may not.

You may assume anything you want, and probably will, same as everybody else.

There is no connection between being Christian and going to church. It is very rare to find an actual Christian church. The bible gives detailed instructions on how to conduct a Christian meeting in 1 Corinthians 12, 13, and 14, and not one denomination follows them. Not. Even. One.

I prefer one-on-one fellowshiping with Him.  I've never been in a church where I didn't come out feeling condemned.  I don't believe God condemns me for not congregating with large groups of people who don't believe as I believe.
