A more thorough explanation:

IN FORO HUMANO

in foro humano (in for-oh hyoo-may-noh), adv. In a human as opposed to a spiritual forum. This means that something may be considered wrong in the eyes of God, but it may not be considered a crime in the eyes of humans.

For example, if someone lies to their friend, it may be considered wrong in the eyes of God, but it is not a crime that can be punished by law. Another example is adultery, which is considered a sin in many religions, but it is not illegal in many countries.

One more example is euthanasia, which is the act of intentionally ending someone's life to relieve their suffering. This is considered a sin in many religions, but it is legal in some countries under certain circumstances.

The examples illustrate the definition of in foro humano because they show how something may be considered wrong or sinful in a spiritual or religious context, but it may not be considered a crime in a legal or human context. This means that while something may be morally wrong, it may not be punishable by law.
