Before the Bible there was the Church. If Protestants don’t believe in the ONE true Church, why on earth do they use the Church’s calendar to celebrate Christmas, Good Friday, and Easter on the same dates observed by the one Church.
Looks like the early Church fathers, some of whom were disciples of St. John, were all wrong. And the thousands of martyrs, saints, and theologians of the last two millennia all got it wrong. And the tens of thousands of historians, Protestant theologians, atheists, and and scientists from all other faiths from ordinary workpeople to Kings and Queens who converted to Catholicism all got it wrong.
What did they miss?
