7. Do not profane His Name

The seventh commandment in Mosaic Law is to not profane His name.

Where in scripture?

Leviticus 22:32

…and do not profane my holy name

Discussion:

This law is seemingly the same as the 26th law - Not to blaspheme. However, per Wikipedia, Jews interpret this law as a commandment not to bring dishonor or shame to God's name by any act or failure to act. Any behavior or act that disgraces, harms, or shames God and his law is regarded as a desecration of God's name.

Also per Wikipedia, Isaac of the School of Rabbi Jannai said that it would profane God’s Name if a person's bad reputation caused colleagues to become ashamed. Rav Nahman bar Isaac said that an example of this would be where people felt the need to call on God to forgive the transgressor.

It would seem that this law requires people, as representatives of their faith, to comport themselves in a manner that does not cause scandal nor cause others to question the faith, its adherents, or the God they worship.

An example of this came in the form of a question in the Ask an Apologist section of Catholic.com. The poster asked why, if the Catholic Church was established by Jesus, aren't there more "good" Catholics. (In Fr. Serpa's answer, he pointed to the many saints of the Church.)

The New Testament and Tradition emphasize the wrong that can result from an individual who acts in such a way as to profane God's holy name.

New Testament references

Matthew 18:6-7 

Whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone hung around his neck and to be drowned in the depths of the sea.  Woe to the world because of things that cause sin! Such things must come, but woe to the one through whom they come!  

Catechism of the Catholic Church

2811 In spite of the holy Law that again and again their Holy God gives them - "You shall be holy, for I the LORD your God am holy" - and although the Lord shows patience for the sake of his name, the people turn away from the Holy One of Israel and profane his name among the nations. For this reason the just ones of the old covenant, the poor survivors returned from exile, and the prophets burned with passion for the name.

Respect for the souls of others: scandal

2284 Scandal is an attitude or behavior which leads another to do evil. The person who gives scandal becomes his neighbor's tempter. He damages virtue and integrity; he may even draw his brother into spiritual death. Scandal is a grave offense if by deed or omission another is deliberately led into a grave offense.

2285 Scandal takes on a particular gravity by reason of the authority of those who cause it or the weakness of those who are scandalized. …Scandal is grave when given by those who by nature or office are obliged to teach and educate others. Jesus reproaches the scribes and Pharisees on this account: he likens them to wolves in sheep's clothing.

Early Church Fathers

St. Thomas Aquinas (on scandal)

It is not the physical cause of a neighbor's sin, but only the moral cause, or occasion; …as when a person without being directly concerned in the sin nevertheless exercises a certain influence on the sin of his neighbor, e.g. by committing such a sin in his presence (this is inductive scandal in a broad sense). For scandal to exist it is therefore essential and sufficient, with regard to the nature of the act and the circumstances under which it takes place, that it be of a nature to induce sin in another; consequently it is not necessary that the neighbor should actually fall into sin …Hence scandal is in itself an evil act, at least in appearance, and as such it exercises on the will of another an influence more or less great which induces to sin.
