Let priests remember, therefore, that the care of all churches must be their intimate concern. Hence, priests of such dioceses rich in vocations should show themselves willing and ready, with the permission of their own ordinaries, to volunteer for work in other regions, missions or endeavors which are poor in numbers of clergy. ... To accomplish this purpose there should be set up international seminaries ... by means of which, according to their particular statutes and always saving the right of bishops, priests may be trained and incardinated for the good of the whole Church.〔''(Presbyterorum ordinis )'', 10〕

The decree ''Presbyterorum Ordinis'' (n. 10) considers that to resolve the problem of the great shortage of priests in certain regions, "it is appropriate also to institute international seminaries". This idea has found application in the ''Redemptoris Mater'' seminaries which prepare diocesan priests for the new evangelization according to the programme of the Neo-Catechumenal Way.
