I wrote extensively about this topic last year covering the historical and spiritual background and the cultural perversions. Click on this link for "Halloween Alternatives" right here on my blog.
Celebrate the Christian Reformation of the church instead.
"Rejoice in the Lord always....
Let your gentleness be evident to all.
The Lord is near....
in everything, by prayer and petition, with thanksgiving,
present your requests to God.
And the peace of God, which transcends all understanding
will GUARD your hearts and your minds in Christ Jesus.
Finally, whatever is true...noble...right...pure...lovely...admirable,
if anything is excellent or praiseworthy
--think on such things."
Philippians 4:4-8 NIV
