“...marriage is foremost a vocation. Two people are called together to fulfill a mission that God has given them. Marriage is a spiritual reality. That is to say, a man and a woman come together for life, not just because they experience deep love for each other, but because they believe that God loves each of them with an infinite love and has called them to each other to be living witnesses of that love. To love is to embody God's infinite love in a faithful communion with another human being.”
