You are correct Walter! New modern dictionaries, like new bible versions, are changing, omitting, rewriting word definitions. Note the changes occurring in newer dictionaries compared to earlier English dictionaries:
An Universal Etymological English Dictionary, 1802, Nathan Bailey
EASTER [easter, of eastre, Sax. a goddess of the Saxons, in honor of whom, sacrifices were offered about that time of year, Ostern, Teut.] a solemn festival appointed in commemoration of Christ's death and Resurrection.
American Dictionary Of The English Language, 1828 (through the 1911 edition), Noah Webster
EASTER, n. [Sax. Easter; G. ostern; supposed to be from Eostre, the goddess of love or Venus of the north, in honor of whom a festival was celebrated by our pagan ancestors, in April; whence this month was called Eostermonath. Eoster is supposed by Beda and others to be the Astarte of the Sidonians. See Beda, Cluver, and the authorities cited by Cluver, and by Jamieson, under Papsyad. But query.]
A festival of the christian church observed in commemoration of our Saviors resurrection. It answers to the pascha or Passover of the Hebrews, and most nations still give it this name, pascha, pask, paque.

Easter (easter), n. [AS. easter, eastran, paschal feast, Easter; akin to G. ostern; fr. AS. Eastre, a goddess of light or spring, in honor of whom a festival celebrated in April; whence this month was called in AS. Eastermonao]. From the root of E. east. See East.]
1. An annual church festival commemorating Christ's resurrection, and occurring on Sunday, the second day after Good Friday. It corresponds to the pascha or passover of the Jews, and most nations still give it this name under the various forms of pascha, pasque, paque, or pask.

Easter (es'ter), n. [AS. eastre, pl. eastron, fr. name of old Teut. goddess of spring, AS. Eastre.] An annual church celebration commemorating Christ's resurrection.

Easter \ester\ n [ME estre, fr. OE eastre; akin to OHG ostarun (pl.) Easter; both fr. the prehistoric WGmc name of a pagan spring festival akin to OE east east]: a feast observed on the first Sunday after the full moon on or next after the vernal equinox in commemoration of Christ's resurrection.
Webster's Ninth New Collegiate Dictionary, 1987 (through 1999), Merriam-Webster Inc.
Easter \ester\ n [ME estre, fr. OE eastre; akin to OHG ostarun (pl.) Easter, OE east east] (bef. 12c): a feast that commemorates Christ's resurrection and is observed with variations of date due to different calendars on the first Sunday after the paschal full moon.
Many modern dictionaries will either omit entirely or include in a footnote the connection of Easter to paganism. Oh, and I guess since the name Lucifer, like Easter, occurs only once in the Holy Bible we need to omit or change the devil's name as well.
"The children gather wood, and the fathers kindle the fire, and the women knead their dough, to make cakes to the queen of heaven, and to pour out drink offerings unto other gods, that they may provoke me to anger." Jeremiah 7:18
"The wise men are ashamed, they are dismayed and taken: lo, they have rejected the word of the LORD; and what wisdom is in them?" Jeremiah 8:9
