[ArrogantBustard]

I think that anyone employed as a teacher of theology (even a volunteer CCD teacher) should profess that oath (or something very like it). And that any Catholic should be able either to profess it in good conscience OR be actively seeking to rectify any discrepancies. Most of us, I suspect, have had our moments of doubt. I certainly have.

Doubt is not the same as lying. I thought the question was about someone who was lying?

By the way if one looks at the oath the only time it uses the word "I believe" is in reference to the Apostle's Creed. The rest of the time, it uses words like "admit", "profess" "hold". Now I don't want to sound like a trial lawyer or a former President parsing the word "is" I suspect some of these verbs accommodate the Christian's struggle with minor doubts. The trouble comes when one actively undermines the doctrine by giving voice to those doubts in a public and declarative manner. Such doubts should be handled in private with a trusted spiritual adviser and not risk the faith of your fellow man. Even more valued is the use of prayer. I am fond of the story of Christ and the man with a daughter possessed with a devil. Christ said she could be healed if he had faith. He responded "I believe, God help me my unbelief."
