The free exchange of consent properly witnessed by the Church establishes the marriage bond. Sexual union consummates it - seals it, completes it, perfects it. Sexual union, then, is where the words of the wedding vows become flesh.

God's plan remains God's plan despite our sin.

Brace yourself! If we take in what the Holy Father is saying in his Theology of the Body, we will never view ourselves, view others, view the Church, the Sacraments, grace, God, heaven, marriage, the celibate vocation...we will never view the world the same way again.

Why was Christ so compassionate towards sexual sinners, especially women? Think of the woman caught in adultery. Think of the prostitute who wept at his feet. Could it be because Christ knew that these women, who had been deceived by counterfeit loves, were actually looking for him, the true Bridegroom?

The idea that 'preaching the Gospel' has nothing to do with sex and that 'preaching about sex' has nothing to do with the Gospel betrays layers and layers of seriously misguided thinking. When we divorce God's love from sexual love, as Pope Benedict says, 'the essence of Christianity' becomes 'decisively cut off from the complex fabric of human life.'

Marriage is a living sign that truly communicates the love of Christ and the Church.

When marriage exposes a person's selfishness and sins it's doing what it is meant to do: bringing our sins and wounds to light so we can recognize them, confess them, and begin the healing process.
