If Christ did not physically rise from the dead, then Christianity is as big a scam and fraud as ,well, Islam
"Yesterday, before going to sleep - although I did not do this to put myself to sleep - I read or rather re-read the work of Cardinal Kasper, and I would like to thank him because I found profound theology, and even serene thinking in theology. It is pleasant to read serene theology. And I also found what Saint Ignatius told us about, that 'sensus Ecclesiae," love for Mother Church. It did me good and an idea came to me - excuse me, Eminence, if I embarrass you - but the idea is that this is called 'doing theology on one's knees.' Thank you. Thank you."
Walter Kasper has openly questioned the historicity of Christ's Resurrection.
