While I don't trust moviemakers generally, I would aver that sainthood and sex aren't mutually exclusive.
Sure. One of the more famous examples is St. Thomas More. He had children. But St. Teresa was a nun. She took a vow of celibacy. She wouldn't be a saint if she broke it.
You're quite right. God made all of us sexed, and thought it was "very good." It's a constitutive element of a sacrament, and a sacred image of the relationship of Christ to theChurch, and of the soul to God.
And St. Teresa of Avila was reputed to be beautiful and also vivacious and charming and attractive, as well as being a virgin and mystic who had what you could call an unblushingly passionate love of God.
What sets off the warning signals is the filmmaker's apparent abysmal ignorance. Anyone who thinks the Catholic Church has "suppressed" examples of feminine holiness, or confined women only to virgin-or-whore images, or -- as the director remarks elesewhere in the article --- that the Church would have burned Teresa at the stake if she weren't so pretty (!)(!), is clearly turkey-stupid about Catholicism.
So is it surprising that I have misgivings about the his portrayal of Teresa's God-given sexuality?
