I disagree to some extent.
For one, its the Catholic who refer to other Christians as heretics or protestants.
A heretic is not simply another Christian And another Christian is not necessarily a Protestant. A heretic is a baptized member of the Roman Catholic Church who disavows a revealed truth. And a Protestant is someone who protests the Catholic Faith as being errant.
These terms were not friendly at their inception.
Neither are heresies and protests against the faith
Then there were the inquisitions which resulted to may ‘heretics’ being tortured or even burnt alive and their properties confiscated.
Catholics are not alone in this category. The reformers participated in such things, no?
However, there is an emergent view from the protestants that the Catholics have gone too far in introducing some teachings whose basis is questionable.
Is this new?
Also by equating the sacred Traditions with the Word of God has not augured well and the rift is just widening.
The written Word of God is Tradition. Oral Traditions were things not written that were handed down from the Apostles.
2 Thessalonians 2:15 (RSVCE)
15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
The worry is that Christ the righteous judge will condemn one of the two as having wandered from the true teaching and made others to follow the same.
So we are not to walk by “worry”, but by faith and love, believing all things and seeking the Faith Confirmed through the Chief Bishop.
If the protestants will be on the wrong, then they will be thrown in hell.
If the Catholics will be on the wrong, the same will be done to them. Though the same Catholic teaching absolve their followers from hell through purgatory.
Matthew 25 (RSVCE)
31 “When the Son of man comes in his glory, and all the angels with him, then he will sit on his glorious throne. 32 Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats, 33 and he will place the sheep at his right hand, but the goats at the left. 34 Then the King will say to those at his right hand, ‘Come, O blessed of my Father, inherit the kingdom prepared for you from the foundation of the world; 35 for I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, 36 I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.’ 37 Then the righteous will answer him, ‘Lord, when did we see thee hungry and feed thee, or thirsty and give thee drink? 38 And when did we see thee a stranger and welcome thee, or naked and clothe thee? 39 And when did we see thee sick or in prison and visit thee?’ 40 And the King will answer them, ‘Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me.’ 41 Then he will say to those at his left hand, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels; 42 for I was hungry and you gave me no food, I was thirsty and you gave me no drink, 43 I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.’ 44 Then they also will answer, ‘Lord, when did we see thee hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to thee?’ 45 Then he will answer them, ‘Truly, I say to you, as you did it not to one of the least of these, you did it not to me.’ 46 And they will go away into eternal punishment, but the righteous into eternal life.”
