Yes, I say this a bit objectively.
The Society of St. Pius X, from the point of view of strict, formal canon law, is not yet fully recognized by Rome because of the current extraordinary crisis in the Church.
On the other hand, the Society of St. Pius X, to my knowledge, provides good priestly formation, similar to what the Church provided before the Second Vatican Council.
So, the concrete question for this young man is that he has to decide for himself and ask God, along with his spiritual director, which place to go.
Of course, the Society of St. Pius X and the other approved seminaries of the communities established by Ecclesia Dei offer a more secure and traditional formation, but the final decision must be made by the young man himself.
Dear visitors of Gloria Dei and all who have already written or who will write a personal message to me. I am grateful for your attention, your kindness, for your spiritual support and especially for your sacrifices and prayers for me. God may reward you!
