I keep re-reading the post and it describes me accurately. The more sins I committ, either venial or mortal, the more I feel that I have to become a priest in order to make up for these sins. Is this unusual?
It is not as unusual as most people may think, and this hardly a new phenomenon. I believe many of the Priests and Bishops that have wrought great ruin against the Church in the past (and those who still do) at one point succuмbed to such a delusion or a variant thereof.
If there is no substantial progress in the interior life and in the attainment to Christian perfection, there can be no vocation to the Priesthood that is of divine origin. As I have written, it is my opinion that such a proclivity is a delusion arising from spiritual blindness and pride, or a delusion that is of demonic origin.
Another thing I struggle with is custody of the eyes. Is it always a mortal sin to stare at a woman? Like lets say a girl in a really short mini skirt walks by and I notice her legs. At what point does that stare become a mortal sin?
From what I have read, that stare becomes a mortal sin when
all of the following happen: 1) you become conscious of the fact that you actually looking at such a thing; 2) feel an involuntary delectation at such a sight (the initial rush of adrenaline through your veins that quickens the heart beats and begins to vex your mind); and 3) you consent with full deliberation to the involuntary delectation and make a positive effort to cultivate it into a greater or more prolonged delight.
A knee-jerk reaction of staring automatically as an indecently-dressed dame walks by is not a sin at all if you do not consent to it, and you try all your best to distract yourself from it (by prayer especially, or thinking about something else, like algebra or economics or death or clowns), even if you feel that initial rush of adrenaline. It is the consent of the will that determines the culpability of an act.
I'm finding this sin, custody of the eyes, my main barrier to receiving communion. Before it used to be fornication, but now it is this. I am wondering if maybe I am being too hard on myself considering that in most major cities young women knowingly and unknowingly dress like whores these days?
If you have reached a point whereat you were formerly given over to fornication and now are struggling chiefly with custody of the eyes, this is very good progress. It is natural for you to begin to be "hard on yourself" because you are undergoing a process of rehabilitation whereby by grace and the exercise of temperance and modesty you are undoing the desensitization to sin and impurity that modern day "culture" has propagated amongst the people.
However, scruples (although initially salutary for the penitent who seeks to repair grave damage) can lead to discouragement and dissipation, and ultimately to give up on the struggle and give oneself over with wild abandon to vice. Remember that prudence is the "Moderatress" of the moral virtues, and you have to know what exactly constitutes sin and what does not.
Yes, if you live in a city populated by indecent women, and you are constrained by exigencies of circuмstance to face this situation on a daily basis, then your culpability would be lessened somewhat. But beware, my friend: for many have been destroyed by cultivating a lax conscience and being once more desensitized to sin and impurity in an even worse and more perilous way than hitherto, for now it would be spiritual blindness and presumption that could lull you into tepidity and make you blind as to the actual state of your soul.
So yes, culpability is somewhat diminished in the particular case you cite, but there is absolutely no excuse: now that you are earnest in overcoming vice since you know the evil and hatefulness thereof, those situational factors that would lessen culpability in others would be so many reminders for you to have recourse to the means of grace (vocal and mental prayer, the Sacraments, devotion to Our Lady, etc.) or else run the risk of incurring greater culpability for having neglected the means of grace of which your coevals may not be aware (or, perhaps, will never be aware). Remember that God never allows you to be tempted beyond your strength, for, as St. Augustine taught, you are either given the strength to overcome temptation by grace or are called to
pray for such strength and grace.
Remember also to pray the Holy Rosary most especially for these intentions: 1) the grace to know with a full knowledge, to feel profoundly, to deplore and to detest your sins; 2) the grace to feel and realize the disorder of your life, to hold it in horror, to reduce it to rule, and amend it, and to correct yourself; and 3) the grace to know and detest the world, to put away from your soul, and keep out of it, all worldly and vain thoughts, and to renounce for ever the world and all its vanities - all this that you may be able to love God all the more generously and profoundly, with all the strength and energy of your being. This is the ultimate renovation of the sacred Baptismal vows that enabled you to become a member of the Mystical Body of Christ.
