i said I wouldn’t eat the food becuase of the communion fast the class being only 90 mins before mass and I said I don’t know if most people follow the fast or I said I don’t think most people do
It is commendable that you would not only respect the Eucharistic Fast (which used to be 3 hours long), but even remind others of this.
It was probably unnecessary to state that you don’t know if most people do this (it may reflect you are used to believe you know a lot, rather than humbly reminding yourself that our ignorance and blindness is very great), and it does reflect a bit of pride to say you don’t think most people do (because it means you are placing yourself above them, or you are placing them below yourself - instead, the Imitation of Christ reminds us: “*It is no harm to thee if thou place thyself below all others; but it is great harm if thou place thyself above even one. *” ).
Of course, both things are indeed venial. However, I do not consider you to be scrupulous, inasmuch as scruples are a condition that affect our spiritual health by distressing us on unnecessary things, while you are simply trying to follow the Lord who said: “be perfect”. And we are very far from that perfection. So keep meditating on your imperfections in such an excellent way, and trying to repair them by substituting them with virtues.
Only do not let these things disturb you, cause anxiety, or take away your peace - this would not be pleasing to the Lord, who desires you to have peace amidst tribulation.
