Some permissible things may hinder your Christian growth. This one night of the year, most eyes are not fixed on Jesus but on a darker image. We need to make it clear as Christians that witches and evil spirits are not funny and are not harmless, even if the people in witch costumes are only play-acting. As Christians, we have plenty of reason to celebrate. While the world around us focuses on activities honouring fear and death, we can celebrate the One who brings life.
Protestants shy away from honouring saints.
Their reluctance generally is based on a fear that the honour will cross the line into worship or prayer to saints. We are to worship and pray to no one but God. But in his Letters to the Corinthians, Paul makes it abundantly clear that he and other saints are only servants men and women like ourselves who are following God. And it is God and God alone to whom we look in our worship and prayers. But with nearly 2000 years of church history, we can well remember many faithful believers whose lives can encourage us in our walk with the Lord.
