How is a Jew declared unclean?

Answer 1

Most of the rituals of purity from the Old Testament require the Great Temple to be serviceable, so Jews today live in a constant state of impurity (often rendered in English as "unclean"). Nobody has to declare them this way; life naturally makes people impure.

Answer 2

In Judaism, there is a concept of ritual (spiritual, not physical) impurity, sometimes translated (inaccurately) as "uncleanliness." Most types of ritual impurity can be purified through ritual immersion in a mikveh. The impurity is brought about (for one example) by contact with a dead animal.

Answer 3

The word "declared" is out of place in most cases. It applies in Leviticus ch.13, when a kohen examines a leper and declares whether or not he/she is ritually impure. (The word "unclean" is a mistranslation.)In other forms of ritual impurity (such as in Leviticus ch.11 and 15, and Numbers ch.19), the person is ritually impure without need for any declaration.

Answer 4

A jewish person who has not showered.
