I was wondering were angels created without the capability of sinning or , "were they created holy, but given free will, just like human beings. They had a period of test, and so those who stayed holy remained in heaven and from the end of that period of test unto eternity, they cannot sin. Those who did not remain holy, such as satan, were cast out and condemned" -H.G. Bishop Moussa
does any1 know any orthodox books or orthodox sources concerning the answer to this question, (because according to our abouna, we asked him this qu. in church and he said that God created them without the ability to sin, but according to Bishop Moussa in his book "youth concerns" the answer is different.
So I was wondering if there are any other sources that answer the question differently
