The word "in vain" is used, as a rule, in a Christian meaning. When talking with the elderly or with the Orthodox, one can often hear a remark from them: do not remember the Lord in vain.
What is "in vain", few people know. The word simply came into use as negative.
The meaning of the word and origin
Turning to the numerous dictionaries of the Russian language, we will see the following meanings of the parsed word "in vain": just like that, in vain, in vain, in vain, to no avail. From here we draw conclusions what is "in vain". It is an obsolete synonym for the above words, meaning something empty and in vain.
It came from the two syllables "v" and "sue", it becomes clear that we are talking about the Old Slavic alphabet. According to the Old Russian language, the word "sui" means "empty" or "vain".
Name of the Lord in vain
The Savior gave his disciples a commandment not to mention His name in vain. And not only to the first disciples - the apostles, but to every person who is an Orthodox Christian.
There is nothing worse when the name of the Lord is mentioned just like that, for the purpose of manipulation or in the event of a conflict. For example, a beggar asks for alms from the church porch and in a sad voice calls to those passing by: "Give Christ for the sake!"
That is, he puts pressure on people's conscience, manipulating the name of Christ. Like, naive people will not be able to pass by, because they are asked for the sake of Christ, and the requestor must be given.
Or during the conflict there is a transition to individuals with mutual insults. And one of the opponents, trying to hurt the other, pronounces the name of the Lord absolutely thoughtlessly, for the sake of causticity.
The call of the name of Christ just entails punishment. God punishes those who vainly pronounce His name.
Conclusion
At first glance, the words seem harmless. But if you dig a little deeper, it turns out - we often use them simply by inertia. Let's think before pronouncing this or that word in vain, and even more so the name of the Lord!
