The teachings of Calvinism are very divisive due to its many inconsistencies. This is not surprising because the founder of Calvinism, John Calvin, is a divisive person. In history, one can learn that Mr. Calvin persecuted the Baptists, and though he was not able to destroy all of them, he succeeded in causing division among them through his erroneous teachings. In fact, the effect of Calvinistic teachings is very bad to the Calvinists themselves because they do not have unity in their doctrines. Some writers say that even John Calvin himself did not understand his own doctrines. Inconsistencies of doctrines show that they're man-made. Man-made doctrines cannot be harmonized with the Holy Scriptures. Those who follow man-made teachings will find it hard to agree with one another. That's why, Calvinists right now are fighting and arguing with each other. Often times, they contradict with their own statements. Let us observe some arguments of two Calvinists as they have stated their doctrinal position in their letters. Read this book and see their inconsistencies.
