I have a question about our fallen human nature.
Most often, the question arises today, about if one is born in sin, more specifically being gay.
What I mean, is that, if someone is born fallen as we are, and if they are broken because of their fallen nature, such as being born blind, being born autistic, being born with predisposition to addictions, being born addicted to crack, or even being born homosexual, does that nature, of being blind, or being already addicted, or even being born homosexual mean that person is sinning or has sinned?
I know we are all born sinners and born with sinful natures. But for example, the Theotokos was born like the rest of us, but she lacked any personal sin. Or that our Church will give Orthodox funerals to babies who die before their baptism or at a very young age because they are understood to lack personal sin and aren't and cannot sin, but are still fallen.
So what about if someone is born with a defect in their psychology? Whether that be a severe handicap such as autism, or whether that be less slight like homosexual attraction, or predisposition to addiction, does that automatically make that person guilty of a sin?
Beyond that, and I guess at the heart of my question, is that, for example, are homosexuals sinning just because they are attracted to the same sex, or do they only sin if they act upon that attraction? Are those pre-disposed to alcohol addiction sinning just because they are pre-disposed to addiction, or do they only sin if they act upon that and get drunk and fall into alcoholism?
My understanding, which comes from the various Priests I've known, from what I've read and what I've heard, is that I'm led to conclude that the Orthodox Church teaches we are born sinners and fallen, but having a certain nature doesn't actually mean we sin just because we have a tendency to something. So for example, at least as I'm taught, we'd agree with a recently statement by the Pope of Rome in that homosexual acts, thoughts & lusts are sinful, but that people who have a homosexual orientation aren't in sin, though they may be broken.
What is the Patristic teaching? I know the typical Augustinian interpretation of sin and inheritance of sin, but what do the rest of the Fathers say? Do we automatically sin by having something broken within us, or are we not guilty of a sin until we commit a thought or action?
