No. Christians are not bound by the mosaic law.
In some religious traditions perhaps. This would be understood as "ritually unclean" and not in any way related to sin. For example, if a man touches blood, even his own, he may be "ritually unclean" until he performs some ritual or until enough time passes. Completely outside of religious contexts, I don't think there is any sense in which uncleanness automatically follows childbirth. It is also entirely unclear how this concept of uncleanness can have any meaning today, even in the context of religion.
Isaiah 52:11 urges Christians to "keep yourselves clean, those carrying the [utensils] of Jehovah." False religion and their accompanying ceremonies are considered unclean, and should be avoided.
Based on bible principles like Colossians 3:5 they strongly advise against self-pleasuring yourself in a sexual way as it can lead to unclean thoughts which can then lead to immorality. As far as between a husband and wife, this would be considered a conscience matter but keeping the marriage bed free from defilement would be a principle considered.
No Jehovah's witnesses are not allowed to donate sperm. This is based on the scriptural principle found at Leviticus 18:20- "you must not give your emission as semen to the wife of your associate to become unclean by it." The principle states that your reproductive powers should not be used for someone other than your marriage mate. So with that in mind, Jehovah's witnesses avoid surrogate motherhood, and any procedures that involve the use of sperm, eggs, or embryos that were donated.
It is unclean because it is a catfish
clean
Isaiah 6:5 - Jehovah's infinite holiness reminded Isaiah of how sinful and imperfect he was.
Lev:11:6: And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
No, "dirty" is not considered a noun. It is an adjective used to describe something that is unclean or soiled.
No, because holidays originated with pagan beliefs. To illustrate say there was a piece of candy in the gutter. Would you pick it up and eat it? No! Just like that candy the holidays may seem sweet but they come form unclean places, and the scriptures admonish us to stay away from unclean things. Isaiah 52:11. For birthdays there are only 2 celebrated and these were of people who were in opposition to God. Gen. 40:20, Mark 6:21.
The Watchtower published by Jehovah's Witnesses, 15th February 2009 page 32 under the heading ''Christian Funerals- Dignified, Modest, and Pleasing to God'' saysRegardless of their ethnic or cultural background, Jehovah's Witnesses strictly avoid any customs associated with the belief that the dead are conscious and can influence the living. Such customs as wake keeping, funeral celebrations, funeral anniversaries, sacrifices for the dead, and widowhood rites are all unclean and displeasing to God because they are linked to the unscriptural, demonic teaching that the soul or spirit does not die.......Therefore, knowing that funeral merrymaking is associated with spiritistic beliefs and immoral activity makes it most inappropriate for true Christians to organize or even attend such celebrations. Being in company with funeral revelers would demonstrate a lack of respect for God and for the consciences of fellow worshippers of Jehovah
Jehovah's Witnesses are the main religious group that does not accept blood transfusions based on their interpretation of Biblical teachings. They believe that blood represents life and should not be consumed or transfused.
