We only use the term "Calvinism" for shortness. That doctrine which is called "Calvinism" did not spring from Calvin; we believe that it sprang from the great founder of all truth. Perhaps Calvin himself derived it mainly from the writings of Augustine. Augustine obtained his views, without doubt, through the Holy Spirit of God, from diligent study of the writings of Paul, and Paul received them from the Holy Ghost and from Jesus Christ, the great founder of the Christian Church. We use the term then, not because we impute an extraordinary importance to Calvin's having taught these doctrines. We would be just as willing to call them by any other name, if we could find one which would be better understood, and which on the whole would be as consistent with the fact
"The old truth that Calvin preached, that Augustine preached, that Paul preached, is the truth that I must preach to-day, or else be false to my conscience and my God. I cannot shape the truth; I know of no such thing as paring off the rough edges of a doctrine. John Knox's gospel is my gospel. That which thundered through Scotland must thunder through England again."
—C. H. Spurgeon
