The Baltimore Catechism and the choosing of the apostles

[pnewton]

In another thread, I was surprised by something from the Baltimore Catechism that stated the twelve apostles were chosen from among the seventy-two disciples. I was surprised because in the Bible the choosing of the seventy-two follows the appointing of the twelve. Furthermore, at least two of the apostles are chosen directly as apostles. Unfortunately, the BC does not include any references. Does anyone have any idea if this was just an error or opinion that was included? Is there any Church teaching on this? I noticed the current catechism does not make such a statement.

I’m just shooting from the hip here, but perhaps they are working from an opinion that the “calls” of the Apostles were first to discipleship, and then to apostleship. After all, Jesus told the fishermen to “follow him” - that is the task of a disciple - and it was only later that he “sent” them - the mark of an apostle. So if the Apostles were part of the original 72, then there is no contradiction in saying they were 1) chosen first and 2) chosen from the 72. Do you have specific scriptural references that suggest the 12 and 72 are and always were discrete groups?
