1. That "science" trumps Christ's teachings.
2. Scripture is to be re-interpreted to adapt to the opinions of men.
Cf. The Syllabus of Errors, Blessed Pope Pius IX and Lamentabili Sane, Pope Saint Pius X
N.B. Pope Benedict XI is the Pope who did the most work to academically correct the errors of Modernism and Rationalism condemned in the above documents, working arduously for more than half a century to answer and correct those errors against the truth of God.
What God is clearly telling us in this confusing time of Pope Francis is that we should continue to read and further the work begun by Pope Benedict. Clarity of doctrine and moral teaching, along with holiness of life, must be furthered, because the enemy is constantly trying to confuse everything.
All this reminds me of Freemasonry, masterful in it's mixture of truth with error.
Remember it well, truth mixed with error is error!
That is precisely what Catholics (true Christians) call heresy. You don't have to be wrong in everything to be a heretic. You just have to err on one essential element of the faith and you are a heretic.
The false notion that there is salvation in vagueness and error and immorality is to be roundly rejected by all honest men!
