“And, indeed, this is already sin, to desire those things which the law of God forbids, and to abstain from them through fear of punishment, not through love of righteousness.”
-Dr. St. Augustine of Hippo
To understand what "Homosexual Attraction" really is we need to follow the logical sequence of Truth:
In the medical, psychiatric, and modern psychology fields, the terms "inclination", "tendency", "urge", "disposition", "predisposition", "propensity", "desire", "appetite", and "attraction", can all be interchangeable. These terms are frequently misused and assumed (wrongly without facts) to mean only the biological. They may or may not be natural or unnatural depending on the object. They may or may not be inherent or freely chosen learned behavior depending on the object. They may or may not be about organic needs or intellectual abstract concepts.
Heterosexual Attraction is what all mammals are biologically naturally created and born with, proven by the scientific natural fact that it is the only basis for natural procreation and survival of the species.
Therefore, Heterosexual Attraction is: normal, healthy, and natural, which makes the absence of it: abnormal, unhealthy, and unnatural.
"Attraction" and "Desire" are one in the same thing whether: natural, virtuous, or disordered.
I am attracted to beautiful things. = I desire beautiful things.
I am attracted to what is evil = I desire what is evil.
I am sexually attracted to a man = I desire to have sex with that man.
I am attracted to short brunets with blue eyes = I desire short brunets with blue eyes.
Question: Are we sexually attracted to every single member of the human race? No.
Question: Do we desire to have sex with every single member of the human race? No.
We are NOT dogs who instinctually hump anything and everything. (No offense to dogs.)
What is the difference between us and brute animals? Our immaterial free will and intellect of our Soul, which is the origin of all that is "disordered" and is also where God instills any and all virtues.
Human beings are the only mammals that have a spiritual immaterial intellect and free will to choose as part of what is called the Soul.
With our non-physical intellect and free will to choose, we human beings can choose to distort and disorder any and all of our perceptions, including desires and attitudes. This includes our perceptions, desires, and attitudes regarding: gender, sexual behaviors, and procreation.
We can choose to desire (want) harmful things and believe false abstract beliefs that make us anxious and inhibit our ability to sleep.
We can choose to desire (want) harmful things and believe false abstract beliefs that make us selfish and lustful that increase our desire for sex.
We can choose to desire (want) harmful things and believe false abstract beliefs that make us greedy and obsessed with food that exacerbate our feelings of hunger.
Therefore we can also choose to desire (want) harmful things and believe false abstract beliefs about our own gender, sex, physical pleasure, and the opposite gender that make us disgusted or unattracted to one gender or the other.
Brute animals cannot be "attracted to" the same gender just as they cannot chose to be attracted to any particular combination of: weight, height, color of hair, or color of eyes within their species. Anyone who makes the false claim that there is "homosexuality" aka "homosexual attraction" within the brute animal species has no objective facts to support it and only projection of their own biased interpretations. It's no different than a pet owner claiming that their pet is morally virtuous or sinful in any way; objectively it's impossible.
According to #2357 of the Catechism of the Catholic Church, Homosexual Acts are "intrinsically disordered".
"Acts" are anything a human being can do or fail to do both interiorly intellectually (includes emotionally) and exteriorly.
[The words "psychological", "intellectual", and "spiritual" are all one and the same thing. For the True original definition of "psychology" is the study of the Soul in both the Greek and Latin. And the intellect is immaterial and a power of the Soul. The intellect and Soul are spiritual; aka immaterial. Therefore, psychological, intellectual, spiritual are all the same interior acts. Interior Acts are: attractions; wants/desires, expectations, beliefs, thoughts, emotions and non-physical feelings.]
Homosexual Acts are sexual actions, both interior and exterior, between the same genders.
Homosexual Attraction is the Desire (want) to do sexual acts with the same gender.
Homosexual Attraction is the psychological genesis; aka origin of Homosexual Acts.
An act (action) of a human being, being "intrinsically disordered" means that its origin; aka its cause; aka the "psychological genesis" has to also be "intrinsically disordered" because "like begets like"; disorder begets disorder; sin begets sin as virtue begets virtue.
This means that Homosexual Attraction (desire to do sexual acts with the same gender), has to be and is "intrinsically disordered".
Homosexual Attraction is objectively a Disordered Desire.
All Disordered Desires are abstract immaterial concepts.
All abstract immaterial concepts originate from the immaterial intellect and free will of the Soul.
Therefore Disordered Desires originate from the immaterial intellect and free will of the Soul.
Homosexual Attraction is a Disordered Desire that originates from the immaterial intellect and free will of the Soul.
As Aquinas states: "But desire is an act of will."
"Augustine proves (De Lib. Arb. i, 11) that "nothing else than his own will makes man's mind the slave of his desire." Now man does not become a slave to his desires, except through sin. Therefore the cause of sin cannot be the devil, but man's own will alone."
- Dr. St. Thomas Aquinas
"But temptation which comes from the flesh cannot be without sin, because such a temptation is caused by pleasure and concupiscence; and, as Augustine says (De Civ. Dei xix), "it is not without sin that 'the flesh desireth against the spirit.'"
- Dr. St. Thomas Aquinas
"hence Augustine says (De Lib. Arb. iii): "Whatever is lacking for a thing's natural perfection may be called a vice."
- Dr. St. Thomas Aquinas
"In human affairs whatever is against reason is a sin." - Dr. St. Thomas Aquinas
“And, indeed, this is already sin, to desire those things which the law of God forbids, and to abstain from them through fear of punishment, not through love of righteousness.” (emphasis mine)
-Dr. St. Augustine of Hippo
Homosexual Attraction is a sin that is freely chosen at some age. Whether it be at the age of 5 (after we were repeatedly sexually molested) when our ability to abstract think; aka "reason" has already begun...or at the age of 12 (because we want to be accepted by someone), which is 5 years after our ability to abstract think; aka "reason" has been completely fully functional, or at the age of 45, (when we decide that our heterosexual marriage isn't "making us happy"). Whatever the age and whatever our "reason", whether we are self-aware of it or not, homosexual attraction is a sin that is freely chosen.
For all of the defensive people who try to negate one Truth with another, using our free will to choose, alone, does NOT determine a person's level of "culpability", nor the level and degree of the sin.
Homosexual attraction; aka desiring/wanting to do sexual acts with the same gender, means that we desire/want to enjoy sexual pleasure with someone of the same gender. Desiring/wanting to do homosexual acts is always with someone with whom we cannot procreate; therefore always "isolated from its procreative purpose".
And according to the Catechism of the Catholic Church:
#2351 "Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes."
According to the Catechism of the Catholic Church, the definition of "lust" is an "Offenses against chastity".
This means that all Homosexual Attraction; aka the "desire for inordinate enjoyment of sexual pleasure", is Lust, which automatically makes Homosexual Attraction a sin that can be permanently healed just like any other sexual sin. This is all great news! Why? Because the fact that Homosexual Attraction is originally a sinful act of the will, means that anyone who is willing to be repentant of it, can seek and receive lasting healing from Jesus Christ for it. Especially with the sexual sins, there is a demon obsessing us that we need to be freed from, who is trying to prevent us from wanting to seek Lasting Healing from Jesus Christ. Yes, there is freedom from Homosexual Attraction, just like any other sin. See all "10 Steps to Lasting Healing and Sanctity" in order to learn how to completely achieve this freedom.
