What are the differences/similarities in the concept of faith as used in Buddhism and Christianity?

There is the concept of faith (śraddhā) in Buddhism. There is also the concept of faith found in Christianity. Both concepts have been translated into the English word faith but in what ways are the concepts different and also are there ways in with the concepts have similarities. I'd find it particularly interesting if anyone knows the original roots of the word faith in Christianity (i.e. what was the original word in Greek or Hebrew) and how the translation compares to how śraddhā has been translated. Do the words have nuances that have been lost in the translation to the simple English word faith?
