And there are many more traditions and related themes that are also pagan.
Wow...oh my. But what's the harm? If we believe it's Jesus' birthday, can't it still be good?
Well, let's confirm what God's attitude is through the Bible. Specifically regarding Tammuz. Ezekiel 8 is all about idolatry in the temple. And see where God calls it detestable? What does he call detestable in verses 14 & 16? And then God's reaction in verse 18?
Oh my! It says women were mourning the god Tammuz...and men were bowing down to the sun in the east! Then God says, "I will deal with them in anger; I will not look on them with pity or spare them. Although they shout in my ears, I will not listen to them."
