As M. James Sawyer once said "there is no such thing as new heresies, only recycled ones." Solomon echos this same concept in Ecclesiastes 1:9 when he says "there is nothing new under the sun." As we understand church history and look at the landscape of some of the teachings that are happening around the church universally there are seeds of heresies being taught, most of the time unintentionally. As a children's pastor I see it all the time when it comes to the idea of how do we talk to kid's about the Trinity. This is a question this gets asked a lot in a kid's ministry group I am apart of on Facebook. In attempts to try and help convey this concept to kid's a lot of times the ideas that get offered in comments are not Trinitarian but rather a form of Sabellianism. What do I mean by this? If you try and convey the truths of the Trinity as an apple, an egg, or whatever else the common illustrations are, that is Sabellianism and it is a heresy. I am humbled by God's grace in the fact that I was once one of those people! Not because I was intentionally trying to be a heretic but I just didn't know. I didn't have a biblical understanding of the Trinity and in my attempts to try and make it understandable I distorted it. This is how most heresies were started. It wasn't from a blatant disregard for the Bible, however some of them were. Most started from the basis of a finite human trying to intellectually explain an infinite God. In our modern day the word heresy or calling someone a heretic has morphed into this idea of someone who doesn't agree with you.
"Heresy is not located in one’s beliefs about baptism, one’s beliefs about the continuation of certain spiritual gifts, or one’s beliefs about a specific view of the atonement. It is a specific and direct denial of any of the central beliefs of the Christian church about the deity and identity of the triune God and about the person and work of Jesus Christ." - Justin S. Holcomb
Do I believe that the Bible talks about those topics mentioned above? Absolutely. To call someone a heretic however because of my difference in opinions about those topics is not accurate however if it does not fall in the bounds of the central beliefs of the Christian church as mentioned in the quote above. The reality that we must face when it comes to our understanding of the central beliefs of the Christian church is that our understanding is all an act of God's grace. I said above I am humbled by the fact that God graciously showed me where I was wrong in my understanding of the Trinity. Most of those growing pains are a natural result in the process of sanctification and the understanding of the Christian beliefs. The difference between a heretic and someone growing in Christ is when God's grace comes to us will we submit our feelings to the Word of God. I mentioned above that most of these heresies started innocently in an attempts to intellectually understand an infinite God. The difference however is when they were confronted with the truth of the Scriptures, there was not a submission to the Word of God. The question we must ask ourselves is will we learn from the councils and the creeds that have been established before us, that God graciously gave us so that we can have an understanding of the central teachings of Christianity that are rooted in Scriptures.
