I do not take part of any religion because i see blind leading blind.
We live in a pagan world and fallen world. You are talking about the Sabbath and claim your Sunday is not the Sabbath however I see countries were everyone closes on Sunday. I know this started as impotition of the Mother of Harlots aka the RCC but people have accepted it now.
Jesus ask to live a holy life as he is holyness so you have to be. However this world is all the contrary and a lot of you accept and have embrace it and act like things are OK when these things are seen by God as abominable.
Changing the Sabbath to "Sun-day" on a "Sun" calendar, pretending Jesus was born on the day of the Equinox can hint you a clue on the world you are living in and whom you are really adoring. Another clue, the vatican has a telescope named "Lucifer", when you see the vatican from above it has the form of a snake, same inside on the main stage, it has the form of a snake. You cannot make this up, google it.
