Theology which conflicts with Christ's teaching is not a reliable source of information. In fact it is not information. It is nothing more than a control mechanism. It is used to divert people away from the moral truth which Christ taught. Irrationality is the product of sin and corrupted theology.
Irrationality creates problems and destroys life.
Therefore, irrationality is a sin. Yet it is glorified by supposedly religious persons as doing God's work. Irrationality supposedly protects God's work from the corruptions of criticism. Nothing that needs protecting from rationality is constructive or God's work. The sin of corrupting theology and calling it God's work is dependent upon an absence of rationality which would expose it for what it is.
