That's not how it was originally established. While a celibate clergy is merely a discipline, it has a tremendous foundation in scripture, the life of Christ, the writings of Saint Paul, and the practice in the early Church. To say that the allowance for priests to marry was how it was originally established is ignore these things.
"Some are incapable of marriage because they were born so; some, because they were made so by others; some, because they have renounced marriage for the sake of the kingdom of heaven. Whoever can accept this ought to accept it"(Matthew 19:12).
