I just noticed something, and I thought I would share it:
Not to oppose error is to approve it; and not to defend truth is to suppress it, and, indeed, to neglect to confound evil men - when we can do it - is no less a sin than to encourage them
Everywhere you look online people attribute this quote to Pope Felix III, not only do they not provide a source, but it was not worded as such and it was not even him!
To be unwilling to disquiet evildoers is none other than to encourage them; he who fails to oppose a manifest crime is not without a touch of secret complicity
- Tanner, Vol. 1, Pt 13, p. 300
What other errors are being willingly and carelessly embraced by the masses I wonder?
