Article: Jehovah's Witnesses are best known for their door-to-door preaching, distributing literature such as The Watchtower and Awake!, and refusing military service and blood transfusions. They consider use of the name Jehovah vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider to be unscriptural doctrines. They do not observe Christmas, Easter, birthdays or other holidays and customs they consider to have pagan origins incompatible with Christianity. Adherents commonly refer to their body of beliefs as "the truth" and consider themselves to be "in the truth". They consider secular society to be morally corrupt and under the influence of Satan, and most limit their social interaction with non-Witnesses. Congregational disciplinary actions include disfellowshipping, their term for formal expulsion and shunning. Baptized individuals who formally leave are considered disassociated and are also shunned. Disfellowshipped and disassociated individuals may eventually be reinstated if deemed repentant.

Question: What do Jehovah Witnesses refuse?
Ans: military service and blood transfusions
