And stayed with him throughout, participating in His passion, just as the encyclicals, perhaps using too florid a language, explain. The Catechism teaches that Mary has a mystical connection with the Church, and the church certianly has a redemptive role a she brings you the saving grace in the sacraments.
So in this case when Jesus speaks to "the disciple", he means all humanity, but when He gives the Great Commission, He is only speaking to those specific disciples.
In both cases Jesus speaks to the Church which is the communion of the disciples. Not to the individual disciples, and not to the entire human race.
it is improper veneration to think that Mary's womb was blessed?
It is not improper, and this is why Jesus does not stop the disciple from venerating her. He does, however, point out the right reason, and that is the custody of the incarnate Word. So correction of the object of veneration it is, disapproval it is not.
What Christ said was to honor the word of God, not Mary.
There is no scripture that states that Mary ought to be held in any special veneration, nor does Christ do so in the Gospels.
This is simply RCC mythology.
In both cases Jesus speaks to the Church which is the communion of the disciples. Not to the individual disciples, and not to the entire human race.
It would really surprise me that the Catholic view is that the Great Commission is meant for all true believers, members of God's Church. In your system only a select few can lead with any authority, so the average disciple would not appear to be qualified to carry out the Great Commission. Do you say that the Great Commission is specifically directed to a group including you?
