I hope not! Being saintly - or holy - means embracing life wholeheartedly, including its comic absurdity and pratfalls, and loving your whole self, which includes your body: eating, drinking wine (if you're not in AA), dancing, singing, and committed, wonderful marital sex. Being saintly means embracing love wholeheartedly, not fear.
Jesus was the epitome of holiness. Look at him! He was at home with his humanity. He enjoyed twelve close men friends and several women friends. He enjoyed partying (the Wedding Feast of Cana - and his first miracle - changing water into wine.) Jesus certainly enjoyed eating - he ate with his resurrected body when he fixed his apostles a fish-fry at the beach. He got mad with a righteous anger - he drove the money-lenders from the temple. He enjoyed Nature and a simple life - he himself was a carpenter and many of his stories were about birds, fish, bread, coins, working men. He also cried at the death of his friend Lazarus, as frustrated with sickness and death as you and I are.
What "holiness" meant for Jesus was very simple as well: Love and Trust Your Heavenly Father with your whole heart. Love your neighbor as you love yourself, including not judging him, because you have the capacity for having faults and sins just as he does. Know and accept that your neighbor is Everybody. Recognize that real, committed love will always bring you to self-sacrifice and your "cross."
In the New Testament, Saint Paul often addressed his letters to the "saints" of a particular city, meaning all those who believed in Jesus Christ and followed his teaching. Paul believed that if you truly believed in Jesus, you were being gradually transformed into "another Christ." You had broken away from society's shallow values and instead valued faith, hope, love, temperance, justice, peace, and had the the courage of your convictions.
It was only much later that the meaning of the word began to change, and people started admiring those Christians who lived lives of extraordinary, heroic virtue. So the community began to call these people "saints" and venerate them after their deaths.
But extraordinary saints, like Mother Teresa, believed in the original meaning of the word "saint." She said "Holiness does not consist in doing extraordinary things. It consists in accepting, with a smile, what Jesus sends us. It consists in accepting and following the will of God." Little Therese of Lisieux spoke of holiness as doing the will of God, and added "and being just what God wants us to be."
Saints are comfortable with who they are because that's who God wants them to be. They don't feel the need to be anyone else. They are satisfied with their own gifts and talents. They accept their own faults with simple honesty. They would laugh if anyone called them "saintly."
Saints are comfortable with what they have. They don't have an insatiable need to possess more. Their own plot of land is their kingdom.
Saints are comfortable with what they don't have. Or at least they can accept the sadnesses, limits, and tragedies of their lives without allowing bitterness to overcome them. They still choose love over any other attitude - and they see love and God everywhere, and want to reflect His goodness and love.
Being a saint is simply being human as Jesus was human, choosing love and trust as the highest goods in your life, and living them out as yourself - the person God made you to be. Accepting who you are, where you are, what you have, and all that happens to you with equanimity is living out God's will for you.
I bet you're doing that already. And that means you're holy. That means you're already working on being a saint. Thank you very much! Because, as Thomas Merton said in his gorgeous book "The Seven Storey Mountain," "People have no idea what one saint can do: for sanctity is stronger than the whole of hell."
