Try this from John Paul II instead
Pope John Paul II to Gathering of Altar Servers

It’s a little more current.
As has been pointed out not Ex-Cathdra.
And if we are looking to keep things up to date how about
this. To provide an extract
"Today, seeing you here before me in St Peter’s Square, I think of the Apostles and I hear Jesus’ voice saying to you: I do not call you servants but friends; abide in my love and you will bear an abundance of fruit (cf. Jn 15: 9, 16).
I ask you to listen to this voice! Christ did not only say this 2,000 years ago; he is alive and saying it to you now. Listen to his voice with great openness; he has something to say to each one. Perhaps he is saying to some of you: “I want you to serve me in a special way as a priest, thus becoming my witness, being my friend and introducing others into this friendship”.
And its also worth noting one of his other comments “In 1935, more than 70 years ago, I began as an altar boy; consequently, it has been a long journey on this path.”. Note that he uses ‘began’, he is saying it has been a long journey which he started, or began, as an Altar boy and now he is Pope. Obviously Pope Benedict considered it part of the process he took to Holy Orders.
The important word is encouraging, not training.
See my previous link for a message from John Paul II to servers, who not only indicated this encouraging for young men for by the same reasoning encouraging young women into religious life.
Training: defined by Wikipedia as “The term training refers to the acquisition of knowledge, skills, and competencies as a result of the teaching of vocational or practical skills and knowledge that relate to specific useful competencies.”
Now by being Altar boys they obtain knowledge about the Liturgy, the skills to serve and the competency to do so well and faithfully. Now that is imparted to them by the tuition in how to serve which comes from the Priest or from older servers who have previously been taught this knowledge, skills and competence. These are all formerly part of the minor orders, which were part of the progression to the Priesthood. They are in short vocational skills which directly relate to what the Priest himself does in celebrating the Mass. In short it fits the definition of training precisely.
See above for a message from Pope Benedict XVI to Altar servers, where he mentions being an Altar boy as part of his journey to becoming Pope.
Actually you’ve not read what Pope JPII said, what you wanted him to say, maybe, but not what he actually said. Here is the way he opens the paragraph “I have spoken of friendship with Jesus. How happy I would be if something more sprang from this friendship!” In that Audience the vocations he mentions the Priesthood, religious life and marriage are all linked by him to that friendship, not to being Altar servers as you are trying to claim. So in short it does not constitute anything like the same weight as the direct link the CDW document drew between being an Altar boy and its assistance in encouraging vocations to the Priesthood.
