Simmons is in denial that Full Preterism leads to Universalism. It is by no means his fault or the fault of the teacher, or the fault of Full Preterism. It is the fault of the student when they go beyond and make their own implications. Right!!! Simmons has said many times Preterism is not to blame. How can a statement made that is clearly Universalistic not reflect the doctrine (ad 70) that professes its truth? Another fish has been hooked and is cooking in the frying pan of Full Preterism.
Kurt Simmons on Universalism
There are many statements taken out of context that might lend themselves to Universalism. If we say that God saves mankind by the blood of Christ, taken literally, that could sound like Universalism. But, that is not what I meant. I think some of the quotes you rely upon are of this type. But even if there are some damning statements, that does not mean that fulfilled eschatology (FP) leads to Universalism. It only means that those statements do. Yes, there are some unfortunate teachings circulating about, but they are no part of my belief system or that of countless others. Hence, it is simply unfair to put us all in the same bucket and condemn all alike.
