Well, TM, I knew we would get to discuss this one soon! LOL!! My thoughts are simple. The first thing I would like to say is that it is apparent that you may have never atteneded a Sunrise Service. I assure that the Resurrection of the Son, is the only observing going on at them. There are no pagan rituals, it is church service outside, early in the morning.
Secondly, the pagans were not the only ones doing something on Sunday morning. They gave the names we use to the days of the week, months of the years. What is your non-pagan alternative to Monday, April 16? If you are going with the pagan argument you must be consistent. The days of the week and months of the years cannot be ok, and Sunday morning a problem....pagan after all is pagan, right? Satan can only take what God has created anad use them or convince humans to use them for his purposes. He comes to kill, steal, and destroy. He is a thief. God made Sunday mroning, satan took it, every other day he could, and anything else created by God(which BTW, is the whole world, Remember,the Earth is the Lord's and the fullness thereof?), to use for his purposes. When you catch a thief with the goods, you don't allow him to keep them. So what satan made up some people and a story, complete with rituals for Sunday morning. I'm sorry, but Jesus trumps Ishtar and her mythological family any day. We give satan more power than he has. He is already lost the war, he is just here trying to win a few battles by having us share his fate, and while he is at it trying to get us to give as little praise and honor to God as he can talk us out of. sunday does not belong to him, it belongs to God, Creator of ALL seven of them. Sunrise, doesn't belong to stan, it belongs to God, Creator of the sun. Praise and worship does not belong to satan, it belongs to God Creator of ALL, including satan.
So you can allow satan to tell you the that you can only worship the Creator of ALL on one day of the week, and the he owns Sunday morning, I know better.
