Celibacy is for those who can handle it.
It was not good for man to be alone, so God created a helper for him. Man is incomplete without a wife.
And even if one CHOOSES to be celibate for the sake of God, that’s a CHOICE. Making it mandatory, a requirement for service, is not Scriptural.
But that never stopped the Catholic church from instituting policy.
Becoming a priest is a vocation and a choice. One may serve God, certainly, in other ways.
Regarding Peter, he was married before an apostle, but tradition has maintained he was celibate thereafter.
Tradition precedes Scripture. Indeed only by Tradition can we know what was the authentic Scripture. You have put the cart before the horse.
