French Reformed Theologian, Henri Blocher, has an interesting take on “original sin”. Blocher contends that we undergo the fact of death in solidarity with Adam like children who share in the sin of their father. Yet we do not undergo the penalty of Adam as if it were ours. Rather, by sharing in his consequences – in the spread of his corruption and death – our sinning certainly happens and our guilt can be reckoned as originating with Adam. Hence his paraphrase of Rom 5:12: “Just as through one man, Adam, sin entered the world and the sin-death connection was established, and so death could be inflicted on all as the penalty of their sins.”
Is that a sufficient take on original sin?
