I think they mean "unsurprisingly".
I wonder how they determined each responder's religion? I assume there are a good number of secular people among the 'Catholics'. Some Catholics treat it like some Jews do -- a cultural thing, not a religion.
1Cr 15:12 ¶ Now if Christ be preached that he rose from the dead, how say some among you that there is no resurrection of the dead?
1Cr 15:13 But if there be no resurrection of the dead, then is Christ not risen:
1Cr 15:14 And if Christ be not risen, then [is] our preaching vain, and your faith [is] also vain.
