Whether Christmas is pagan or not, that depends on each person's point of view, because the word says in Romans 14. 22 Blessed is he who does not condemn himself in what he approves. 23 But he who doubts what he eats is condemned, because he does not do it with faith; and everything that does not come from faith, is sin, 17Because the kingdom of God is not food or drink, but justice, peace and joy in the Holy Spirit, so in my humble opinion, would do the same with these Christmas festivities, If you celebrate them with faith believing that this pleases God, then for you it would not be a sin.
