Predestination

Christadelphians affirm that God's purposes are certain and that he foreknew and predestined the coming of Christ and the framework of redemption. The Abrahamic and Davidic covenants, for example, established God's intention to bless the nations through a specific lineage — and these purposes are unchangeable. In this sense, Christadelphians affirm a robust divine predetermination of the plan of salvation.

However, Christadelphians reject Calvinist unconditional personal election: the idea that God has unilaterally determined from eternity which specific individuals will be saved and which will be condemned, apart from any response on their part. In Christadelphian theology, individuals are genuinely free to respond to or reject the gospel, and their response determines their standing before God. Salvation is offered to all who hear the gospel and respond with faith and baptism; it is not limited to a predestined elect.

The Christadelphian framework also includes the concept of 'responsible and non-responsible dead' at the judgment: those who have heard and understood the gospel are responsible before God and will be judged accordingly; those who never had the opportunity are not held responsible in the same way. This ethical concern for fairness in God's judgment reflects the Christadelphian emphasis on human moral agency and accountability.
