A doubting conscience is worse than a conscience in error.
To clear the vision of your conscience, you need humility. You need humiity in two ways.
First, you need the humility to accept the fallibility of your conscience. Its important to form our consciences, but its also important to trust and follow our consciences. This means that if our conscience is in error, we are still required to follow it. We have the responsibility to educate our consciences to help us make better decisions in the future, but we need the humility to accept our current ignorances, misunderstandings, etc.
The second way you need humility, is the humility to look at yourself honestly. Scruplocity can also has an element of pride toward the scruplocity. **“I’m not like a dissenter. I’m hard on myself for all these little things. In fact, I’m such a holy person that I’m sort of saint-like in that I’m petrified of committing the smallest sin.” ** False humility may come into play as well. We may tell ourselves we’re not prideful because our internal dialogue toward ourselves involves name-calling and the like.
As such, while the sexual sin may be there, our pride may be so strong that even when we go to confession, we only see the sexual sin. It bothers us only because we want vainglory – rather than a sincere love of God. If that is the case, than you need to spend a greater effort battling against your pride than your sexual sins. In this case, the pride is keeping you from God by robbing you of the ability to a sincere repentance of any of your sins. Instead you confess “just in case.” You confess benign things…as if repentence were a matter of belittling yourself and naming the sin.
As such, should you receive the Eucharist? I’m going to probably tell you the hardest thing. YOU need to make the judgment for yourself. You will probably still have fears of being wrong if you decide to go up, but simply pray to God in the line “Lord I want to please you. This is my judgment. Please help me to grow in humility so that I can accept the fallibility of my conscience.”
