Perhaps all ye Evangelical Bashers should spend some time in the Book of Romans;
14:4 Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
14:5 One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
14:6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
I am quite sick of the continual evangelical baiting and bashing that goes on here. The obvious intent of the OP was to cast aspersions on the brethren
I don't know how any truly serious student of the Bible can conclude that the Sabbath is on Sunday except perhaps by embracing replacement theology you can somehow eliminate the Jewish Sabbath from history.
Perhaps you should MYOB while searching YOUR OWN HOUSE house for leaven.
This is because you don't understand theology. The Sabbath we celebrate was born on Sunday, the day of the Resurrection of Christ, the "eighth day" of creation, the New Jerusalem.
