Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle. 2 Thes 2:15
I have no recollection of when it was exactly but it ws at least 3-4 decades ago, and I also don't remember the source whether it was Rome or the U.S. Bishops, but the depiction of the Sacred Heart as a disembodied heart was forbidden.
Buzzkill. The Vendee soldiers wore just a disembodied heart as their coat of arms, hope they are okay.
