In hoc signo vinces/With this sign you shall conquer

No no thats wasnt a saint (although later he became).He was the Emperor Constantine a pagan .Christianity was still illegal in the roman empire thenThe Catholic church wasnt even a thing The Christian church as we know it wasnt even a thing ,rather there were these christians groups in every city.Now if this is a legend i dont know thats why i asked here .I tried to search it up on the internet but i didnt found anything besides pages that basically "retells"the event

Also i dont think the miracles of the saints are pretty accurate since theyve seem to be written by aunothorized authors or something?
