I have discerned and spoken with them before. I have even met them before, in fact. They are a great bunch of people. One thing that should be noted is they are not a community as of yet. They take vows every single year, from what I have been told. Anyway, so long as you have a high school education (Which you need in order to join anyway) if they feel you are called, they will send you. You would go to Mount Saint Mary’s Seminary, I believe. But ultimately it depeonds depends on your calling. One thing I have experienced a lot is fear that I may not get ordained or be allowed to join a community, but through a year and a half of discernment I have learned not to worry. If God calls you to the Priesthood you will be ordained, though it may be tough. If you are called to enter a community so long as you cooperate you will fulfill all the requirements and enter. Trusting is something we struggle a lot with today, but we all need to learn that we can trust no thing more than God. He truly wants what is good for us, and when He wants something for us, we will get it, rain or shine. Though I typically do not like the book of Psalms (Never was one for poetry), there is one verse from there which I recommend memorizing for when you feel worried about your vocation:
“Trust in the Lord for He is good; happy are those who take refuge in him.”
I will pray for you and your discernment. I would recommend contacting the Knights of the Holy Eucharist if you have not done so yet. They will answer any questions you may have and if you are old enough they will plan a visit for you.
May the peace of God which surpasses all understanding guard your heart and mind in Christ Jesus.
