To set mercy in opposition to
the indissoluble bond of marriage is to set mercy against fidelity, and for someone who believes in the God of Jesus Christ that entails an irresolvable internal contradiction.
In its intrinsic supernatural reality,
marriage includes three goods: the good
of exclusive, personal, reciprocal fidelity (the bonum fidei), the good
of welcoming children and educating them to know God (the bonum prolis), and the good
of the indissolubility or indestructibility
of the
bond, the permanent foundation
of which is the
indissoluble union
of Christ and the Church, which is sacramentally represented by the
marriage (the bonum sacramenti).
