Passover celebrates death, and deliverance from death, not resurrection. Besides we do not know how New Testament Jews celebrated Passover. We only know of later Jewish customs. So don't try that one on.
What we do know is that our LORD introduced a new feast which enables us to participate in His death and confirm our part in His new covenant, and told us to participate in it whenever we drank wine. I wonder whether you do that?.
How do you know how God views Easter? You are simply saying how YOU view Easter, which isn't really very important.
My view is that God's heart was thrilled as hundreds of millions around the world celebrated the resurrection of His Son.
I don't think He cares a jot about eggs and bunnies and buns which are just seen as a bit of fun for the children. But I DO think that He is grieved by the judgmental attitude revealed on here against His sons.
