"Do not take God's name in vain " is not quoted at all in the NT - prescriptively or descriptively and James 2 says to break one is to break them all.
Boy, Oh Boy are you WRONG. Of course the NT teaches "Do not misuse God's
name" prescriptively.... both positively and negatively. What version of the Bible do you read? The Reversed Version?
A listing of verses in the NT which prescribe "Do not take God's
name in vain" negatively:
CURSING USING GOD'S NAME IS A SIN BECAUSE IT IS USING GOD'S NAME TO WISH EVIL ON SOMEONE OR SOMETHING.
James 3:10 Out of the same mouth come praise and cursing.
Romans 12:1414 Bless those who persecute you; bless and do not curse.
Swearing is a sin when we use God's name to tell a lie.
Mt. 26:69ff
69 Now Peter was sitting out in the courtyard, and a servant girl came to him. “You also were with Jesus of Galilee,” she said. 70 But he denied it before them all. “I don’t know what you’re talking about,” he said. 71 Then he went out to the gateway, where another servant girl saw him and said to the people there, “This fellow was with Jesus of Nazareth.” 72 He denied it again, with an oath: “I don’t know the man!” 73 After a little while, those standing there went up to Peter and said, “Surely you are one of them; your accent gives you away.” 74 Then he began to
call down curses, and he swore to them, “I don’t know the man!”
Swearing and using God's name unnecessarily is also a sin
Matt 5:33-37 33 “Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’ 34 But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne; 35 or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. 36 And do not swear by your head, for you cannot make even one hair white or black. 37 All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one.
Jame 5:12 Above all, my brothers and sisters, do not swear—not by heaven or by earth or by anything else. All you need to say is a simple “Yes” or “No.” Otherwise you will be condemned.
It is a sin to lie in using God's name to cover up false teaching.
Mt. 15:8
“‘These people honor me
with their lips,
but their hearts are far from me.
9 They worship me in vain;
their teachings are merely human rules.’[
c]”
It is a sin to lie in God's name to cover sin in a person's heart.
Acts 5:11f
Now a man named Ananias, together with his wife Sapphira, also sold a piece of property. 2 With his wife’s full knowledge he kept back part of the money for himself, but brought the rest and put it at the apostles’ feet. 3 Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? 4 Didn’t it belong to you before it was sold? And after it was sold, wasn’t the money at your disposal? What made you think of doing such a thing? You have not lied just to human beings but to God.” 5 When Ananias heard this, he fell down and died. And great fear seized all who heard what had happened. 6 Then some young men came forward, wrapped up his body, and carried him out and buried him. 7 About three hours later his wife came in, not knowing what had happened. 8 Peter asked her, “Tell me, is this the price you and Ananias got for the land?” “Yes,” she said, “that is the price.” 9 Peter said to her, “How could you conspire to test the Spirit of the Lord? Listen! The feet of the men who buried your husband are at the door, and they will carry you out also.” 10 At that moment she fell down at his feet and died. Then the young men came in and, finding her dead, carried her out and buried her beside her husband. 11 Great fear seized the whole church and all who heard about these events.
Mt. 23:23-28 “Woe to you, teachers of the law and Pharisees, you hypocrites! You give a tenth of your spices—mint, dill and cumin. But you have neglected the more important matters of the law—justice, mercy and faithfulness. You should have practiced the latter, without neglecting the former. 24 You blind guides! You strain out a gnat but swallow a camel. 25 “Woe to you, teachers of the law and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence. 26 Blind Pharisee! First clean the inside of the cup and dish, and then the outside also will be clean. 27 “Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean. 28 In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness.
Mt. 15:7-88 “But you are not to be called ‘Rabbi,’ for you have one Teacher, and you are all brothers. 9 And do not call anyone on earth ‘father,’ for you have one Father, and he is in heaven. 10 Nor are you to be called instructors, for you have one Instructor, the Messiah.
We sin when we use God's name superstitiously
Mt. 7:22 22 Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your
name and in your
name drive out demons and in your name perform many miracles?’ 23 Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
