Sorry, but when people judge those who Go to Church on Sunday as breaking the law and not following the sabbath/ That is judging people When you have no idea if they follow the true sabbath or not.
The letter of the law states commands specific to the law. The spirit of the law is to realise the letter is not enough to show us how to follow it. Or even all things which would be consider breaking it.
An example is as said before. Do not commit murder to follow the letter. we can say since i have not killed anyone I am following gods command Yet the spirit says if you even think it, you are found guilty of breaking it.
You explain yourself better and we come closer in our understanding, but when we say scripture stands behind that Sabbath is Saturday, it is not judging people, to my way of thinking, but judging about the Sabbath day.
Before, you spoke against following law, it seemed to me, saying that was following the letter of the law. You explain better, now.
By going over the posts, I see people determined to not have a Saturday Sabbath as judgmental of the people who are obeying this. No one I have read, has said that those who only find a Sunday church are all wrong, only those who say those who found a church who has Sabbath are wrong.
I find more content and pleasure within myself when I follow what God says instead of how man says God wants. I don't think it is wrong to do this. Although, I do find wrong things about following man. That is NOT judging people, it is judging to find out what God wants.
