Your post reaffirms what many of us have learned on this forum -- Presbyterians ignore the Gospels to such an extent that they do not even recognize the words of Jesus Christ and feel free to flaunt that with impunity.
I am fully aware of what the OT commandments are, but it seems that Presbyterians haven't read the words of Christ in the Gospels where He comments on the commandments. Or, if they have read them, they have ignored Christ, and gone back to the OT for their list. Doesn't surprise me. Especially since the Pressy's don't seem able to understand.
