Yes it is, Jo. I was merely pointing to a different way of looking at sin in our traditions, but the Western Chruch understand sin the same way as we do. I would say the Latin expression of feeling abandoned by God is a profoundly human experience (our tendency is to blame someone else, always). The Orthodox take is Patristic and therefore not something an individual will automatically understand.
I am always amazed when I read that Jesus experienced being abandoned by the Father before He expired. It shows that He was fully Human as well.
You'll be happy to know that since Vatican 2, the Catholic Church has been moving away from that
The Vatican has steadily been moving back to Patristic ways and nothing makes me happier, believe me.
You aren't the only one!
Brother in Christ
