Do you think the Apostles hid eggs and hunted for them? The (prolific)rabbit and eggs (sign of fertility) got mingled in with traditional religious observances. The term Easter was used in the post and therefore I merely pointed out . . . and we all got sidetracked. As I pointed out I have seen "Easter" in some KJ versions but have not checked any Douay-Rheims for cross reference.
But just for emphasis, please don't take it amiss if I say this: the bunny and egg things are just innocent fun. I don't read that the Apostles were opposed to making hot cross buns on Shrove Tuesday; or serving a cake with a coin in it on Epiphany; or decking the halls with boughs of holly; or a bride tossing her bouquet to the unmarried girls; in fact, fun and frivolous things are very often connected with high and holy things, and no harm done.
G.K. Chesterton said something (something witty of course, and dang me, I can't remember what it was) about if you take a very slight two-degree wrong turn in theology, you end up with the singing silenced and the dancing banned, and all your ornaments smashed on the floor. That could be the Puritans -- or the Taliban.
