Take heart brothers and sister. From the beginning of the Church, The Church has felt deeply the struggle against the twisting of Christ's message and the Church He left behind. I found this passage from St. Eusebius very encouraging. Note: He wrote his history just after Christianity became the approved religion in the Rome Empire.
I hope it helps others out there, too. I highly recommend Eusebius' 'History of the Church' as reading material for Lent. It makes me glad I live in modern America. Right now anyway, we can not be persecuted like Catholics were in the first 3 centuries after the Pentecost.
