Not long ago I heard the provincial of a certain congregation say that in his congregation, missionary formation was almost non-existent...

...despite these words written 50 years ago in Art 26:

For anyone who is going to encounter another people should have a great esteem for their patrimony and their language and their customs.
It is very necessary for the future missionaries to devote themselves to missiological studies: that is, to know the teachings and norms of the Church concerning missionary activity, to know along what roads the heralds of the Gospel have run in the course of the centuries, and also what is the present condition of the missions, and what methods are considered more effective at the present time.

to know along what roads...I wonder how many seminarians, I wonder how many priests and religious, have ever heard of people like Matteo Ricci,  Hudson Taylor etc?

Jesus, by your Holy Spirit, please give all Christians, especially priests and religious, a missionary spirit
