The symbol of the Crucifix demonstrates the power of God, as explained in 1 Cor 1, and demonstrates the love God has for us by giving up His only begotten Son for suffering and death for our sake. If His sacrifice is too difficult for you to contemplate, that is fine, but stop with the business that ours is a "dead Jesus". It is not true, as you've already been told. But I guess persisting in the lie is in accordance with the Reformation's "sin boldly".
