When you say Yes to God unconditionally, you have no idea how far this Yes is going to take you. Certainly farther than you can guess and calculate beforehand... but just how far and in what form? At the same time, this Yes is the sole, non-negotiable prerequisite of all Christian understanding, of all theology and ecclesial wisdom.
Even if a unity of faith is not possible, a unity of love is.
The Holy Spirit knows what a particular age's most pressing need is far better than men with their programs.
