This word you are giving to each other is not just any word, but a solemn promise, a vow before God. This is a huge step to take into the unknown. The reason you take this step with confidence after much careful consideration is because it is not just any word you are giving each other, but, as I said a solemn vow before God, in other words it is a covenant between the two of yourselves and God. That is why we describe marriage in the Catholic Church as a sacrament. The second reading which you chose for your wedding contains Paul s description of Christian loving.
Love is always patient and kind.
It is never jealous, etc. A couple does not begin marriage with this perfect love. The couple grows in loving and grows by loving. Love is hard work. Sometimes love will mean you will have to suffer, if not the love is a disguised form of selfishness.
