By no means! Easter is the primary Christian holiday celebrating the resurrection of Jesus Christ the Lord.
However, the English word "Easter" may have pagan connotations. The Anglo-Saxon priest Venerable Bede in the 8th century derived it from the Anglo-Saxon spring goddess Eostre.
Of course, our days of the week, too, spring from the names of pagan gods:
Sunday
Sun god
Monday
Moon god
Tuesday
Tiu, Germanic god of war
Wednesday
Odin, Norse supreme god
Thursday
Thor, Norse god of thunder, weather, and crops
Friday
Frigga, wife of Odin and Norse goddess of married love and of the hearth
Saturday
Saturn, Roman god of agriculture
And the names of the months, similarly are deeply infected with the names of pagan gods:
January
Janus, Roman god of doors and gates
February
Februus, ancient Italian god, and festival of purification
March
Mars, Roman god of war
April
Aprilis, Roman republican calendar month, considered by the Romans as sacred to Venus
May
Maia, Roman goddess of spring
June
Juno, Roman goddess of women and marriage
July
Julius Caesar, defied Roman emperor
August
Augustus Caesar, defied Roman emperor
September
Seventh (month of early Roman calendar)
October
Eighth (month of early Roman calendar)
November
Ninth (month of early Roman calendar)
December
Tenth (month of early Roman calendar)
You see, the NAMES that we use -- indeed, our entire vocabulary -- is filled with pagan references of Anglo-Saxon, Norse, Germanic, and Roman gods and goddesses, since the vocabulary developed before Christianity came to England. But the CONTENT of Easter -- at least as true Christians practice it -- is a celebration of the Resurrection of Jesus Christ. The old pagan celebrations of Easter are for those who don't know Jesus. But a meditation on Jesus' cross, his death, and his glorious resurrection are to be the focus of Christians.
Don't get hung up on the name "Easter." But focus on the joy we celebrate when we recall Jesus' rising from the dead on that Sunday morning, that "Easter" morning, 20 centuries ago.
