you should always post the scripture for reference with things like this....

as for easter and christmas... yeah, you are exactly right on they are pagan holidays... some priest or roman catholic "leader" of some sort (i don't remember who) decided to start having christmas and easter on whatever those pagan holidays were so that it would look and appear like "everyone" was celebrating christ... (i could be a bit off on this... but i know i'm pretty close to the reasoning)

most christians know this.... if not they def need to...

but you've also gotta remember... those pagan holidays are kinda long gone and forgotten about... the days that everyone celebrate christmas and easter now are just that... christmas and easter...

do you celebrate either of them????

if so... why??? your agnostic....

further more... if you do, and aren't celebrating them for what most christians do... are you going back to the paganistic(- is that even a word? lol) roots of the holidays yourself?....

no... you're just happy to have some time off work get some extra presents and what not...

i'd be more than willing to bet God is pretty pleased with the fact that christians/catholics.. turned what were once pagan holidays/rituals into two different days of the year that even non christians are basically forced to think about Him/Jesus......
