Is there such a thing as a holy day?

Response to comment [from a Christian]: "One or more that you think God esteems, and wants us to esteem, above others?"

CathOlics have holy days of obligation. They get drunk and fornicate on all the other days. Ro 14:5

Response to comment [from a "Christian"]: "When you called me a Satanist you sure messed up your Holy day. didn't you."

He did his job calling you out for the antichrist you are (Eph 5:11). You're welcome.

All days belong to us. Ps 118:24

As a reminder LA is number 11 on Satan, Inc. (TOL Heretics list) in "The 'Jesus is not God' people (Non-trinitarians) category.

Response to comment [from a Christian]: "If you're Catholic, not only are their Holy Days, there are Holy Days of Obligation. Forget to participate in a Holy Day of Obligation and you just bought yourself some years in purgatory."

Better down a Eucharist tout suite (Matt. 24:4-5, 24).
