Are you saying that you don’t believe in obeying the Commandment: “Keep holy the Lord’s Day?”
Where does it say that? Not once in scripture does it call the first day of the week "the Lord's day".
Just a couple of facts... 1) The 10 commandments are old Testament with the purpose of leading men to Christ..
Gal.3: 24Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith. 25But now that faith has come, we are no longer under a tutor.
2)The "commandment " says Keep the day "holy" (that is set aside) it says nothing about going to mass .. Rome says that
Mark 2: 27Jesus said to them, "The Sabbath was made for man, and not man for the Sabbath. 28"So the Son of Man is Lord even of the Sabbath."
Colossians 2:16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day.
