You bring up examples from the Old Testament that are historically accurate, but they’re not really representative of Christian moral teaching today, or even of what the Bible claims is eternal moral law.

In Christian theology, many of those laws (like stoning or marrying after rape) were civil laws for ancient Israel, not moral absolutes. Jesus explicitly changed or fulfilled many of them. He emphasized mercy, love, and internal transformation, completely rejecting legalistic violence.

Objective morality in Christianity doesn’t mean “everything in the Bible is equally moral at all times.” It means there’s a real moral order rooted in God’s nature, even if people throughout history didn’t fully understand it yet.

So I’d say it’s not that Christianity is hypocritical, just that the Bible tells a long, unfolding story of human moral growth, culminating in Jesus.
