I once asked my priest if 1.forehead 2. Chest 3.left chest 4. Right chest was acceptable because that formed a Petrine cross rather than Jesus’ cross (which is the point) and he said that as long as you have the intention to make an honest sign of the cross, you are good. Then, months later, I made a Petrine cross in front of him and, seeming to forget what he told me, he said that wasn’t legitimate and that I should make it 1. Forehead 2. Belly button 3. Left chest 4. Right chest so as to resemble Jesus’ cross.
Now, I was with some older Catholics and they saw me making the Petrine cross and corrected me, saying that the inverted cross was used by early persecutoes of Christians as a way to mock. So, they told me to do 1. Forehead 2. Belly button 3. Left chest 4. Right chest.
But, Today I saw the POPE make a Petrine sign of the cross and I’ve seen countless priests and laypeople make it.
What. Is. The. Way. Lol.
