The entire Christian spiritual, ethical and moral “system” is Christian insofar as it begins with God loving us in and through Christ, and ends in our becoming one with that Love, which is nothing less than God’s own self, given to us and known by us as the Holy Spirit. How we address all the spiritual, ethical and moral questions in life as Christians is what happens in between. Or, as St Augustine put it: “Love, and then do what you will”.

Real love is about moving out of oneself towards another in self-gift, while at the same time opening oneself up to another’s gift of themselves to oneself. Christian spirituality and Christian ethics/morality are both grounded in real love really lived.

Real love is about vulnerability, which takes an enormous amount of courage, strength and commitment (or “fortitude”). Real love begins in a kind of wonder before the awe-inspiring, indeed terrifying, mystery of another who loves us. It grows and takes possession of one’s whole being with a profound sense of respect, indeed reverence, for the Other who loves us. And this awe and this reverence are what give rise to the courage, the “fortitude”, to risk everything in committed giving of oneself to that Other in love—which is precisely what is meant by Christian spirituality and ethics/morality, or “the Christian life”.

Real love is about desiring the good of those we love, wanting and working towards the very best for them, desiring that they may flourish according to their nature as the image of God.

In GNFL this understanding of Christian life is developed with emphasis on these theological and anthropological principles:

• Christian ethics/morality is one with Christian spirituality; and both are grounded in the God who loves us, and who therefore enables us to grow in love.
• Real love—God’s love—costs. Real love isn’t cheap. Real love costs, but it is God whom it costs. And God “pays the price”, as it were, in person: Jesus, giving himself even unto death for love of us.
• At its deepest core, the Christian life (spirituality and ethics/morality) is about God and the Spirit.
• Our ethics/morality flows from our spirituality, our encounter with God in Christ; it flows from who we are as Christians, from our life in Christ, from who we are as creatures alive through and with and in the Holy Spirit, the very Self and Life of God loving us.
• To speak of Christian life in a meaningful way, to do Christian moral and mystical theology properly, or to work out a genuinely Christian ethics, we must always begin where we mean to end: in God loving us.
• To do anything less than that—to start with principles, ideals, the law, virtue, values (even “gospel values”), etc.—is to focus on ourselves as though we were anything less than loved-by-God, anything less than destined for communion with God, and with one another in God. To start with any of these things is to reduce our ethics to ideology, our morality to legalism, our spirituality to selfishness, and therefore our theology to idolatry, by reducing ourselves to our egos, and our lives to a meaningless existence between the cradle and the grave.
