"President" is an occupation, not an honorary style of address like "His Eminence". It's fine to call LBJ "President Johnson", as President was his occupation. But we would not call him "The Honorable President Johnson" or anything. Similarly, we can call the cardinal "Cardinal Francis Arinze" to provide context to the mention of his name. But "His Eminence Cardinal Francis Arinze" is unnecessary. Hope that helps. By the way, if you intend to contribute regularly, you might wish to create an account.  (t)
