Yes. It's pretty hard to change what Calvinists believe in, and it's even harder to change what John Calvin wrote. Read it yourself, and write a refutation if you care to.
Calvinists
The Calvinists believed in the concept of predestination, which teaches that God has already determined who will be saved and who will be condemned, regardless of any actions taken by individuals. This belief is a central tenet of Calvinism, a Protestant Christian theological system developed by John Calvin in the 16th century.
This is not a simple question as there are various types of predestination. The direct opposite of Calvinistic predestination (the main theory) is Arminianism. The difference put simply is "Arminians believe that they owe their election to their faith, whereas Calvinists believe that they owe their faith to their election." However, as you can see Arminianism still requires election and so is still a form of predestination. The true opposite of the theory of election is simply free will. Each human being is given choice over his destination!
If I am not mistaken, Calvinists believe in predestination, which means that it is known whether or not a person will go to Heaven after they die before the person is even born.
The issue of predestination was the major issue especially between calvinists and Lutherans.
No. Predestination is not part of Methodist doctrine and is not believed by most Methodists.
yes they did
This is a vexed question. John Wesley did believe in predestination, just a difference kind of predestination than his Calvinist brethren. Wesley was Arminian in his doctrine. He had disagreements over the issue with his friend and fellow worker George Whitfield, who believed in the Calvinist form of predestination. Hard predestination (Whitfield's kind) understands God to be ultimately in charge of deciding whether each individual is "saved" or not. Soft predestination (Wesley's kind) recognizes that God knows who will be saved and who will not, but God does not decide that for each individual.
John Calvin
No, Calvinists are not Catholic, they are Protestant Calvinists.
They're almost the same thing. Presbyterians believe in baptizing babies, while Calvinists don't. That's the only major difference.
the calvinists only perform Baptism and Eucharist
