O foolish Galatians, who hath bewitched you, that ye should not obey the truth?
"For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins"
Did you read that? If we sin. How do we know if we sin? 1 John 3:4 tells us sin is the transgression of the law. So we have to refer back to the law to see what is sin. But you (Catholics) are telling people to deliberately sin by not worshiping God on the Sabbath. Who is it now that is in jeopardy of Hell? If you read the Word of God, it ain't me.
Jesus wasn’t a Sabbatarian - He fulfilled the Old Covenant.
We now live in the New Covenant and we worship the Lord on the Lord’s Day - the first day of the week.
Sabbatarians are not Christ believers
