That’s sad to hear and I’ll pray for you. Remember what Jesus told us, if the world hates you it hated Him first. Where some people get these ‘devil’ ideas is beyond me. As you have learned, what they believe to be the Church is nothing like what it is. Sometimes I think their wrath comes from the cognitive dissonance of trying to follow Christ outside His Church.

"As some of my readers already know, before converting to Catholicism, I was a “born-again” Evangelical/Pentecostal teacher who was originally raised in a Baptist Church. My journey of faith led me through the rigors of Fundamental Protestantism, and the depths of outright anti-Catholicism. I cannot begin to tell you how many times I had heard a pastor preach to his congregation that the Catholic Church is an “unbiblical cult” and the prophetic “Whore of Babylon” written of in the Book of Revelation.
I eventually decided to research the origins of this wretched organization called the Roman Catholic Church. In doing so I quickly discovered that all the authoritative literature on the topic were keen on quoting each other, but very little cited information more than a couple hundred years old. In fact, most cited a single book written in the middle 1800s called “Two Babylons,” by Alexander Hyslop. This particular author constructs an entire volume of accusations against the Catholic Church, based on his own superficial connections between this or that ancient ritual, but does virtually nothing at all to back his claims with original source documentation. In fact, finding any original source documentation to support these claims, that dates prior the Reformation Era, is virtually impossible. It seems as if accusations against Catholicism developed as a product of the Reformation itself, and not vice versa.
As a result of this, I began reading the history of the early Church and quickly found a plethora of original source documentation dating back to the first few centuries of the Christian age. What I learned was shocking! and turned my whole world upside down. The early Christians were all Catholic! That’s right, the earliest Christians, meaning those who were persecuted by the Caesars and fed to the lions, believed in the transubstantiation of the eucharist, prayed to the Virgin Mary and the saints, recognized the primacy of the pope, and made offerings for their loved ones in purgatory. Oh sure, they didn’t use all the fancy terminology I just cited, but the core of their belief system was virtually identical. Knowledge of history spelled the end for my Protestantism."
