Who did Jesus most criticise?We're all different and I'd not use precisely the same language as Sam.
I used to think that it was the people who were sure of their own salvation.
I now see that as misleading.
I think Jesus most criticised those who were sure of somebody else's damnation.
Those were the people whom Jesus damned.
I think I'd say 'I used to think that the people Jesus was criticising was those who were sure of their own salvation. I now think that he was criticising those who were sure of the damnation of others.'
I'm not sure that Jesus 'damns' those who think that they know who is damned. But I do think that we are enjoined many times in the New Testament not to make these judgements.
There are those who wonder how can I say that Jesus is Lord if I don't know who is damned? My response is that I know who is saved and I don't need to know who is damned. That's God's job.
