I agree with the post from HMiS. My son is in first year seminary with the SSPX. He is beginning the years of discernment. He may or may not actually take Holy Orders but is certainly given ample time and opportunity to investigate whether he does have a calling.
The requirements are rather simple:
- be a Catholic male in good standing with the Church
- have generally a decent reputation (be ready to have a priest who knows you recommend you to the seminary)
- be healthy
- well educated (at least highschool with good marks)
- family background is also considered
This portrait fits just about any young healthy Catholic male. The difference is an orientation to a desire for this call. There must at least be a willingness to investigate the possibility of a priestly vocation. And you may also have the qualities for the monastery rather than a parish priest.
There are many steps to taking Holy Orders over a period of 7 years so there is ample time to consider whether or not it is for you. Don't hesitate by feeling that it is too big a commitment. Develop a healthy humility and trust in God.
Read the lives of great priests such as Jean Vianney - Patron Saint of parish priests, Don Bosco, Father DeSmedt, Padre Pro or St. Piux X for inspiration.
I will remember you all in our family rosary this evening.
