Okay. As a young man, I was a traditionalist, and even a Calvinist who thought it my mission to promote predestination and eternal security (actually unconditional security). However, I was interested in what the early church, right after the days of the apostles, taught. My thinking was that they would have been in a better position to understand what the New Testament writers meant than we, who were born 2000 years later, and are not all that familiar with Christian practice at that time, nor the subtleties of the language. So I began to read early Christian literature. I learned that the early church had communion every Sunday and that they practised body ministry. This early literature also convicted me that my Calvinistic beliefs were in error.
Many years later, I began attending a church in my area which had many practices and beliefs which I had been reading about in early Christian literature. Once when I attended a summer camp, I heard one of the leading brethren, say to another at the dinner table, “I never could believe in an eternal hell.” I was shocked! What had I gotten myself into? This was a cult! I walked around in that camp grounds in a daze, and very disturbed and upset. Then the Lord seemed to say to me, “Don’t worry about this. All will become clear.” So I relaxed and enjoyed the rest of the camp meetings.
Whenever I read my bible after I arrived home, when I read some rather familiar passages, I found to my amazement that they taught the reconciliation of all to God. Soon I accepted the truth of the reconciliation.
Now I could have been spared my discomfort at the camp, my disturbing thoughts, my emotional upset, if the brother had not spoken against eternal hell. If he had spoken for the reconciliation of all to God, providing scriptures, I could have eased into the truth that hell is remedial. So my suggestion in approaching “traditionalists” is to provide scriptures which teach the reconciliation of all things to God. Do not mention hell at all until they have dealt with the reconciliation of all to God. Then they will be less likely to reject out of hand as a heresy, the truth of universal reconciliation to God.
