Yep! Anyone Christian that reverts to 1st covenant Judaism or Mosaic Law is under the curse and might as well return to Paganism.
In the Word of God -- we find
"Do not take God's name in vain" in Exodus 20... the TEN Commandments.
In the Word of God we are told that the unit of TEN is the one where "
The FIRST commandment with a promise" is the 5th commandment Eph 6:1-2 and so it is still binding on all mankind.
In the Word of God - we are told "
what matters is KEEPING the Commandments of God" 1 Cor 7:19
In the Word of God - Christ said "
if they do not listen to Moses neither will they listen though one rises from the dead" Luke 16
I choose - the Word of God
============================
I am glad that even these Sunday sources affirm ALL ten of the Ten Commandments for Christians.
