A point by point comparison of Church Teaching compared to the teaching of Pope Francis:

"Why have we chosen to remain anonymous? Well, just like our Spanish counterparts, we do not want to give our Bishops problems. It is already not easy to be a Bishop these days… With their consent, but shielding them from any possible repression, we happily make time for this translation – between already too many pastoral obligations – out of love for the Church and for the good of souls.
It is not for us to judge anyone. That is the duty of the competent authorities. And we are just modest priests. All we want is to let the Magisterium of the Church be known. It alone separates error from Truth – human opinion is always fallible. So do not expect more from this page: we will throw a bit of light in a very confused world at a time when no one says a word.
With this page we attempt only to fulfill our duty, in obeying St. Paul: “I charge you in the presence of God and of Christ Jesus, who will judge the living and the dead, and by his appearing and his kingly power: proclaim the word; be persistent whether it is convenient or inconvenient; convince, reprimand, encourage through all patience and teaching. For the time will come when people will not tolerate sound doctrine but, following their own desires and insatiable curiosity, will accuмulate teachers and will stop listening to the truth and will be diverted to myths. But you, be self-possessed in all circuмstances; put up with hardship; perform the work of an evangelist; fulfill your ministry” (2Tm 4:1-5)."
