I don’t agree that makeup hides the truth.
I think it hides what is false.
When Adam and Eve sinned, corruption entered the world. Blemishes, age spots, sun damage, spider veins, dark circles–these are not “truth,” but are the results of living in a sinful, FALLEN world. Our bodies are constantly decaying because our world is fallen. Even if we ourselves strive to be sinless, the sin of others has far-reaching effects that hurt even the most innocent among us. That’s why little babies and children die of cancer–not because of their personal sin (heaven forbid), but because of the sin of all mankind. That demonstrates how powerful sin is.
We all know that when we see a friend ravaged by the effects of breast cancer, that the flawed body we are seeing is NOT the body that God intended for her to have. We all know that someday, she will be given a new body, with no flaws. We SEE this with our spiritual eyes.
When we are baptized, the process begins by which we are restored to our former status as perfect human beings. We have the hope that one day, we will be like Jesus.
In the meantime, we attempt to bring God’s Kingdom to this earth. (I know I’m phrasing that badly.) We build beautiful churches (usually) and write/sing beautiful music that lifts us out of earthly life and reminds us of our heavenly home. We try to surround ourselves with goodness and loveliness. Would anyone say that this is “covering up the truth?” Well, yes, it is, because we are NOT good and lovely in our souls…yet. But why not work to look that way and act that way until we ARE that way?!
Why shouldn’t we cover the “false” part of our faces, the part that is there only because of the sin and resulting corruption of humans, and strive instead to show to the world a glowing, shining face with no flaws, perfect, the way God originally created all humans? Does this not glorify God? The world cannot always see with “spiritual eyes.” All they can see is the OUTSIDE, and if the OUTSIDE somehow makes them think of God and His Beauty, well, that is a good thing. That’s why we spend the money and time to build beautiful church buildings instead of just holding Mass in a gymnasium somewhere.
And if we do use a gymnasium for some reason, e.g., a children’s Mass, we strive to make it pretty, perhaps with a lovely chair for the priest, or a backdrop with a royal color. Is THAT covering up the truth, that it’s just a gymnasium? Yes, it is, but I’m glad! Aren’t you?
Certainly if you believe that your face is perfect now, go right ahead and display it and glorify God. But many of us are attempting to glorify God not by hiding our real selves, but rather, by displaying ourselves the way we REALLY look if people could see the REAL us, the way God meant for us to look before sin and death entered the world.
