Rejoice in God! God needs to be a part of our everyday life: Just like eating and breathing. Believing on The Lord Jesus Christ and His sacrifice for our sins, reverses the eternal consequences of sin and the fall of man. We should not celebrate matters of unrighteousness, but God Who gives us life and breath.
America has Irish immigrants to thank for bringing Halloween (aka Samhain) with them, though the Scots have been implicated as well. If the British fed the poor wretches, maybe we would've been spared it & also St. Patrick's Day.
Even the French, notwithstanding their historic Catholicism & love of holidays, have no counterpart to "Alloween," which I understand is making slow inroads there. For once, I heartily encourage French traditionalists who oppose such Yankee imports.
