Eastern Catholic Churches affirm God's sovereign choice and predestination as taught in Romans 9:18-21 within the patristic framework that harmonizes God's sovereignty with human freedom. The passage is understood as revealing God's absolute authority and providential governance. Following Eastern patristic theology, particularly the Greek Fathers, Eastern Catholics understand that God's predestination is based on His eternal foreknowledge of human choices and responses. This maintains both God's omniscience and human moral agency. The mystery of how these coexist is acknowledged as beyond full human comprehension but both affirmed as true in divine revelation.
