Have you read Eusebius? He was the bishop of Caesarea who wrote a history of the whole Church leading up to the Nicaean council. One of the accounts he gave was of Christian women in the flower of youth and fertility, who were going to be raped first, then killed, for their confession of faith in Christ. Rather than subject themselves to debasement, they instead killed themselves first, denying their murderers and rapists the wicked desire of their hearts.
But mostly the martyrdom accounts were men, and very many of them bishops, who were variously burned, eviscerated, dismembered, stabbed or otherwise cruelly punished, while still alive, all of whom ultimately succumbing to their injuries. The one that really spoke to me was when martyrs were dismembered, finger by finger, toe by toe, limb by limb, all while carefully kept alive and conscious, and their pieces were fed to wild animals right in front of them, until they died.
This was all because they wouldn't call Caesar "Lord," and wouldn't participate in sacrifices offered to emperors and to pagan deities. They only called Jesus of Nazareth "Lord," and they only offered the sacrifice of the Mass (the Eucharist; the Lord's body and blood) to God the Father.
It's helpful to learn about history so that we can interpret our current reality in the light of relevant context. Things could be far, far worse than they are for Christians right now.
