“A marriage which does not constantly crucify its own selfishness and self-sufficiency, which does not ‘die to itself’ that it may point beyond itself, is not a Christian marriage.
The real sin of marriage today is not adultery or lack of ‘adjustment’ or ‘mental cruelty.’
It is the idolization of the family itself, the refusal to understand marriage as directed toward the Kingdom of God.
This is expressed in the sentiment that one would ‘do anything’ for his family, even steal.
The family has here ceased to be for the glory of God; it has ceased to be a sacramental entrance into his presence.
It is not the lack of respect for the family, it is the idolization of the family that breaks the modern family so easily, making divorce its almost natural shadow.
It is the identification of marriage with happiness and the refusal to accept the cross in it.
In a Christian marriage, in fact, three are married; and the united loyalty of the two toward the third, who is God, keeps the two in an active unity with each other as well as with God.
Yet it is the presence of God which is the death of the marriage as something only ‘natural.’
It is the cross of Christ that brings the self-sufficiency of nature to its end.
But ‘by the cross, joy entered the whole world.’ Its presence is thus the real joy of marriage.
It is the joyful certitude that the marriage vow, in the perspective of the eternal Kingdom, is not taken ‘until death parts,’ but until death unites us completely.”
