Metaphysical scandal
It is often assumed that what puts the Church at odds with contemporary society is its ethical teaching. Many cry out for change in this area. Quite apart from the merit of considering what might be a Catholic response to particular, perhaps new problems in ethics (something each age is called upon to do), I consider the assumption false. I do not think the principal skandalon is ethical. I think it is metaphysical.
The holiness of God! The splendour of his glory, made manifest in Christ through infinitely gracious condescension! These core realities, which to the founders of Cîteaux were axiomatic, seem strange to an age whose outlook is wholly horizontal. We are children of that age. Of this we must ever be aware.
