Anti Pope

First, it must be noted that no one can receive the petrine munus, if there is someone already holding it. And no one can cease holding it unless he dies or has in a juridical act expressly renounced it. Also, no one can be elected to receive it, while someone holds it, and after his death or renunciation of it, claim is prior election is sufficient to obtain it. Elections must be posterior in time to the conditions adapt for the validity of an election. Thus Jorge Mario Bergoglio has never held the petrine munus and by his 10 year pretense has no claim to it.
