The Catholic Church does not consider Calvinism, a theology developed by John Calvin in the 16th century, to be heretical. However, it does disagree with certain aspects of Calvinist theology, particularly the belief in double predestination, the doctrine that God predestines some individuals to eternal salvation and others to eternal damnation. The Catholic Church teaches that God desires the salvation of all humanity, and that every person has the free will to accept or reject God's grace.
The Catholic Church also disagree with the beliefs of the "Limited atonement" which is the belief that Jesus died only for the elect. The Catholic Church teaches that Jesus died for all humanity, and that his sacrifice on the cross is sufficient for the salvation of all people.
In summary, while the Catholic Church does not consider Calvinism to be heretical, it disagrees with certain aspects of Calvinist theology, particularly the belief in double predestination and limited atonement.
