What the article that you posted calls heresy, is what I believe with all my heart as a Catholic. I cherish it and try my best to live my life accordingly. Not every Catholic chooses to follow, but I do. Maybe if they read what the Church teaches in all its fullness, they would follow with joy and love. Maybe those who leave don't understand all the Church has to offer, often those who find it empty, or don't feel they get anything out of it, don't put as much into it as they should. It's a difficult road, but a joyous one if you make it the center of your life. Then God is always with you, and you with Him, and the Fruits of the Holy Spirit begin to fill you.
The article you posted was framed by the author as information for Evangelicals and Fundamentalists to promulgate against Catholicism. Do you promulgate the heresies of the Muslim faith, proselytizing to them? To Wiccans? Atheists? Satanic masses take place in public. Are you there preaching God to them?
I am a Catholic. You will not shake my Faith. I do not choose to impose my Faith on others. I state my truth with, "I believe." And I do, with all my heart.
God bless you!
Muslims, Mormons, and many others believe in false religions also. That doesn’t make it correct.
Do you promulgate the heresies of the Muslim faith?
“Salvation Includes the Muslims
841 The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind’s judge on the last day.”
