Marriage, a lasting and personal union of a man and a woman, is a solid institution which offers a frame for a relationship of fidelity and the founding of a family. Instead of trying to invent alternatives to marriage we should ask ourselves: what can we do as Church and as politicians to promote successful marriages? If the Catholic Church is in favour of marriage it is because she is convinced that marriage is the life-form which corresponds best to human nature and it represents a splendid opportunity for the personal growth of husband and wife.
