I was ofended because I don't need the Catholic Church's permission to be called a Christian.
I'm just going to share my personal experience as a Christian.
I was raised in a non-denominational Evangelical, and then later Pentecostal, church background. During that whole time, up until my early 20's give or take. I never experienced a Catholic, or an Episcopalian, or a Lutheran, or an Orthodox ever tell me I'm not a Christian.
However, tests of whether I was a "real Christian" were common in the church circles I lived in.
In my 20's when I was moving away from the theological views of my upbringing, and began looking at more historic, traditional churches (eventually I became Lutheran, which I still am). I never had to prove or have permission to call myself a Christian to any Catholics, or Lutherans, or Anglicans, or etc.
But I have consistently had to defend my status as a Christian when talking with less traditional Christians.
I've never had, for example, a Catholic attempt to make me prove to them I was a Christian. They just accepted that I was, because I believe in Jesus, they believe in Jesus, and whatever might divide us doctrinally didn't change the fact that we were both Christians.
But I have had various Evangelicals do that.
When I was an Evangelical I regularly had to share my testimony, which went something like, at the age of four I asked Jesus into my heart and become my personal Lord and Savior. I never mentioned all the spiritual turmoil surrounding that which I wrestled with, having my testimony was important because that was made me fit in, that was my Christian ID.
Now, of course, when I share my personal story of a life of faith, I mention that there was never a time when I didn't believe in Jesus. I have memories that go back to when I was quite little--I can remember being four years old and going through the Sinner's Prayer with my parents. Heck, I can remember when I was two and I fell into a swimming pool at my mom's cousin's house and she had to rescue me. I remember my little brother's face when my dad lifted me up to show me him just hours after he was born. In every memory I have, I already believed in Jesus. Because there was never a moment that went by from the day I came into this world crying that my parents didn't talk about Jesus.
However, when I've shared that story, without mentioning the "Sinner's Prayer" part when I was four, I've been accused of not being a real Christian. I've been told that nobody is born a Christian, and then I get compared to calling myself a car for visiting a garage. Because I had to prove--I needed permission--to call myself a Christian.
But it wasn't those churches which talk about Baptism, the Lord's Supper, etc which questioned or required me to get their permission to call myself a Christian.
I have regularly found myself wondering how so many churches which regularly talk about "grace alone" and "faith alone", when push comes to shove, refuse to accept either grace or faith when it comes to salvation. Instead, what matters--or so I have been told over and over again for around four decades now, is the stuff I'm supposed to do, the works I have needed to do, in order to be saved and call myself a Christian.
I realized a long time ago that I was raised hearing "grace alone", but there was no grace in what I was being taught. I was raised hearing "faith alone", but trusting in Jesus was never enough. I was raised hearing "Christ's work alone", but what Jesus did wasn't enough. It was always up to me, to prove my worth, to prove my Christian certification, by having done the right things, and meeting a highly specific set of criteria. And that meant that, in a very tragic sense, I had grown up never really hearing the Gospel. Assurance, I was told, was necessary for me to be saved; but I never had assurance growing up, because I was constantly told to look at myself. Did I "mean it" when I asked Jesus into my heart, for example. Was I actually sorry for my sins when I asked Jesus to be my Savior--a difficult question I imagine for any eight year old to answer.
What I wasn't told, and what I really needed to hear, was "It's not up to you, Jesus died for you, trust Him." Because the day I finally heard that, my life changed. That wasn't the day I became a Christian. That wasn't the day I "got saved". But that was the day when my view of God turned upside-down, and I began to see God and know God through Jesus.
