Yes, and I asked her where is she getting that from. Is that not a fair question? Or are you going to answer for her?
She did not state it as absolute doctrine, or even claim that it was church doctrine, but that's what it seemed to her. More along the lines of an observation. It is one that does have some Scriptural support, however....Psalm 103: 19-22
betty boop is Catholic and Catholics undergo catechisis as part of becoming Catholic. Catechism answers all questions regarding what Catholics ought to believe and what the Church in her wisdom teaches. Catholics are not free to interpret scriputures privately or to make doctrinal statements that are not in line with the Church teaching.
That being said, the Psalm you quote from does not suggest 'unfailing' angelic obedience to God's will. It only mentions those who do obey his will. No 'programming' suggested here.
It may be appropriate to mention here that Judaism does differ from Catholic faith on this issue. Jews believe that angels have been created as obligate servants of God and are not free to disobey him. That's why Judaism rejects any notion of Satan being a 'fallen' angel, or fallen angels in general. In Judaism, ha satan is considered a loyal son of God, and Lucifer (a Latin creation from the Latin word for light) refers to the Babylonian morning star god.
Well then I guess I must not be Catholic yet, for I have not undergone catechesis.
