I am what I am...C or K

Have you ever wondered why we say Cephas (sē'fəs) instead of (Kē'fəs). I started saying Cephas (with a K sound) and I like it. I shall take my stand on my mountain of 'C" should be "C" and "K" should be "K". okay...I'm not making enough sense. Well, look at the time. I think I took my meds already too.

Then there are all those Bible names I am going to learn. I have a good dictionary that will help my with the pronunciation.
