Implicitly then, in celebrating Father's Day, we would wish to celebrate the role of fathers within a stable family unit and so we wish to celebrate marriage too. It is still true that the most stable families, those likely to be together after five years, are those who are bound in marriage between one woman and one man, and especially as they work sacrificially and mutually towards a lifetime together.

So what role does the church play in all of this and indeed what has God to say about it?.
God has a lot of good things to say about the raising of children and it is always in the context of family life.
When God talks about family life it is always in the context of marriage.
It is very clear that God regards marriage as a covenant.

What is a covenant?
an agreement between two parties based on promise, which includes these four elements:
an undertaking of committed faithfulness made by one party to another or each party to one another;
the acceptance of that undertaking by the other party;
public knowledge of this undertaking and its acceptance;
the growth of a personal relationship based on and expressive of such a commitment.
It isn't difficult to apply such a definition of covenant to marriage as human marriage is used in the Bible to illustrate Goddess covenant with his people and Goddess covenant with us is used to illustrate or model human marriage.
As one writer put it:
... both covenants have:
1) An initiative of love, inviting a response and so creating a relationship;
2) a vow of consent, guarding the union against the fitfulness emotions;
3) obligations of faithfulness,
4) the promise of blessing to those faithful to the covenant obligations, and
5) sacrifice, the laying down life, especially in the sense of old independence and self-centredness;

I think you learn about that type of sacrifice in marriage and then again very acutely when children come along some time after. Indeed for parents and perhaps especially for fathers today it is salient to apply this concept not just to the marriage relationship, but in some part to the parent/child relationship.

Parenting too is
an initiative of love - love between a husband and wife, which in part will become focused in the third party of a child or children;
there is a vow of consent whether before or sometimes after conception (!) at least on the part of the parents towards the children,
there is an obligation of faithfulness, to love and care and nurture that child to adulthood;
there is a promise of blessing (often the Bible speaks of children as a blessing and it's true; and
there most certainly is sacrifice. If people are unwilling to sacrifice something of the inevitably more self-centred lifestyle of pre-children days I have to ask why they have children in the first place, children are not chattels, possessions to be paraded;

These covenants, marriage and parenthood are each a moral commitment which should be honoured.

Yet a covenant can be broken; divorce and the fragmentation of a family expresses tragedy and sin. Marriages don't just break, as covenants don't just break, they are broken by parties to that covenant, that marriage, that family. We are morally responsible for our marriages and our families, we cannot be absolved that responsibility.
