I know that I do desire to keep the sabbath as it exists on Saturday and do not judge others on the issue but believe what Paul said about it that every man should be fully convinced in his own mind whatever point of view he has on it.
I believe that the whole issue of judging as concerning a sabbath day can be applied both ways. Some who actually observe the sabbath are judged as being "too legalistic" in their point of view; and I would say to this that Colossians 2:16 applies to this as well as the other.
Every day of the week is the Sabbath if you are in Christ. Man can observe any of these days if he wishes.
But to judge another on a certain day in not allowed! We must acknowledge that Christ is the Sabbath in the New Covenant.
Romans 14:5-12
