Answer:
I think the answer in your question is either ‘Witnesses’, ‘Martyr’ or ‘Christian Martyr’.
Explanation:
In Christianity, a martyr is a person considered to have died because of their testimony for Jesus or faith in Jesus. Martyrs are people who believe in their faith so strongly that they're willing to die for it. The original Greek word means “witness,” and these people are witness to their love of Jesus Christ and the Church in that they'd rather die than betray their God.
