Really? So you are calling Jesus a liar? Matt 16:18
Were you to understand what the true keys of the kingdom are, and what the true kingdom is, perhaps you would realize how erroneous the RCC interpretation of Matt. 16:18 is.
The Augustinian Amillennialist “kingdom” of Roman Catholicism, the paganized pseudo-Christian tyrant called the RCC that ruled the dark ages - aptly named - most certainly is not the kingdom that Christ spoke of.
Moreover, the paganized pseudo-Christian impostor “Holy Father” ruling from his throne in Rome throughout the dark ages, guilty of the most heinous crimes in the name of Christ, most certainly did not then and does not now have the keys Christ spoke of.
