Calvin on Apostolic Tradition

"Irenaeus had seen the followers of the apostles. He and Tertullian mention the small number of bishops who had been in succession to the apostles up to their time. Many old people were still alive then during whose lifetime the very words uttered by the apostles had been well known from the reports of their fathers. So it is not surprising if they put forward as apostolic tradition what at that time not only had been accepted in common by the first churches, but was considered fixed and unchangeable as the sure doctrine of the faith which Paul, Peter, and their other colleagues had only lately delivered to them. But even Origen, whose time was not much different from theirs, counts among the essentials of the faith certain opinions which, if Pighius [his Catholic opponent] does not anathematise, will get him stoned by his own side too.....I urge readers merely to compare those ancient times with our own; then they will be able to judge how much sincerity or alternatively disgrace there is in his [Pighius'] building his case on [the Father's] support."
