CANON 4. If anyone maintains that God awaits our will to be cleansed from sin, but does not confess that even our will to be cleansed comes to us through the infusion and working of the Holy Spirit, he resists the Holy Spirit himself who says through Solomon, "The will is prepared by the Lord" (Prov. 8:35, LXX), and the salutary word of the Apostle, "For God is at work in you, both to will and to work for his good pleasure" (Phil. 2:13).
CANON 5. If anyone says that not only the increase of faith but also its beginning and the very desire for faith, by which we believe in Him who justifies the ungodly and comes to the regeneration of holy baptism -- if anyone says that this belongs to us by nature and not by a gift of grace, that is, by the inspiration of the Holy Spirit amending our will and turning it from unbelief to faith and from godlessness to godliness, it is proof that he is opposed to the teaching of the Apostles, for blessed Paul says, "And I am sure that he who began a good work in you will bring it to completion at the day of Jesus Christ" (Phil. 1:6). And again, "For by grace you have been saved through faith; and this is not your own doing, it is the gift of God" (Eph. 2:8). For those who state that the faith by which we believe in God is natural make all who are separated from the Church of Christ by definition in some measure believers.
Orange in no way is a affirmation of double predestination or Calvinism.
The Second Council of Orange concerns Pelagianism and semi-Pelagianism, rejecting both. It affirmed Augustine against Pelagianism; it denied the interpretation of Augustine as strict predestination.
In the Council of Trent, the Church condemned as heresy any doctrine asserting “since Adam’s sin, the free will of man is lost and extinguished” rejecting Calvinism’s total depravity.
