What particular comments from Calvin do you have in mind?
Since Irenaeus was only one person, wouldn't you also need to demonstrate this was the universal position of the church?
More specifically, what is the universal position of the Church on predestination?
This is a good treatment of the Calvinist TULIP:
A TIPTOE THROUGH TULIP
By JAMES AKINPREDESTINATION means many things to many people. All Christian churches believe in some form of predestination, because the Bible uses the term, [See Rom. 8:29-30, Eph. 1:5, 11. For the Catholic Church's teaching on predestination see Ludwig Ott, Fundamentals of Catholic Dogma, 242-244, and William G. Most, Catholic Apologetics Today, 114-122], but what predestination is and how it works are in dispute.
In Protestant circles there are two major camps when it comes to predestination: Calvinism and Arminianism. [Calvinists are followers of John Calvin (1509-1564). Arminians are followers of Jacob Arminius (1560-1609), not people from the Republic of Armenia]. Calvinism is common in Presbyterian, Reformed, and a few Baptist churches. Arminianism is common in Methodist, Pentecostal, and most Baptist churches.[ In Catholic circles, the two major groups discussing predestination are the Thomists and the Molinists, the followers of Thomas Aquinas (1225-1274) and Luis de Molina (1536-1600). Thomists emphasize the role of grace, while Molinists emphasize free will. Neither school ignores grace or free will].
Even though Calvinists are a minority among Protestants today, their view has had enormous influence, especially in this country. This is partly because the Puritans and the Baptists who helped found America were Calvinists, but it is also because Calvinism traditionally has been found among the more intellectual Protestants, giving it a special influence.
