They continue 2 mandate (they & ALL non voluntarily - non optionally) observe all these man made pagan holiday's cuz they R so called established tradition's, (loved?!) by the world (the fellow human clueless, misc of humanity itself). 2 observe these (pagan ie: 12/25 Roman SUN god's deem day & even Easter) holiday's & make them each individually part of the Catholic faith isn't harmless or irrelevant cuz they R lies & the Holy Bible NEVER teaches us 2 observe them.
