Maronite Catholic theology, following the Catholic tradition influenced by Augustine and Aquinas, affirms that God's predestination includes God's foreknowledge of how humans will freely respond to grace. Romans 9:18-21 is understood in the context of God's universal salvific will (God desires all humans to be saved) and the cooperation of human free will with God's grace (synergy). God's mercy and human freedom are both real and genuinely operative in salvation.

The Maronite theological tradition, rooted in the Syriac fathers (particularly John of Apamea), maintains a sophisticated understanding of grace and free will working together. God's grace is always offered; human acceptance or rejection of this grace is genuinely free. Predestination includes God's eternal knowledge and allowance of human free choices.
