This Sunday's Gospel Acclamation:
'I am the handmaid of the Lord:
let what you have said be done to me.'
Mary's yes, or fiat as it is commonly referred to, is the ultimate act of faith in God's divine plan. It is a simple and humble acceptance of the Father's will over and above Mary's own dreams and aspirations.
Mary's fiat is the complete sacrifice of the self in favour of the interests of another. It is, in that sense, very much like marriage. Marriage, as a Sacrament, is the complete giving of oneself to another in love. Love, in this sense, is a sacrifice and we should always guard against reducing it to a mere emotion as is often the case in today's world. Love is wanting the very best for your spouse and this, of course, should be reciprocal, so that at all times each spouse is striving for the very best for the other and each lives in the security of an endless cycle of sacrifical love.
Mary, in saying yes to God, not only shows us how to be completely obedient to whatever God wants for us. Mary, in saying yes, also shows us how to love.
