If you are a Catholic today who is not rejoicing at the canonization of two popes, please ask yourself "why".
Perhaps you have not read the biographies of these two popes. If not, I would recommend doing so.
Perhaps you have not understood that politics are not religion and religion is not politics.
Perhaps you do not understand mercy and forgiveness, repentance and change.
Perhaps you have not read the lives of the saints, such as that of St. Teresa of Avila, or St. Jerome.
Perhaps you do not understand that some few saints are born saints, but most become saints in their lifetime.
Perhaps you are looking at people who surrounded these saints rather than at the saints themselves. Judgments such as this have no place in the minds of good Catholics.
Perhaps you are confusing holiness, which is perfection on earth, with political astuteness or infallibility in writings. Even the writings of the great saints are not perfect, or infallible, even though the persons became saints.
Perhaps you have not understood the reason why these saints are being canonized today.
Perhaps you need to pray and read about what real holiness is.
