Great question!! Thanks for asking!! No, the notion of ecclesial vocations is entirely consonant with the emphasis of Vatican II. Actually, the accents on Union with Christ and serving the Church so that it may truly be the Church God calls it to be attributed to ecclesial vocations, allows this emphasis to be understood in terms of a diversity of vocations all of which call persons to an exhaustive holiness. I can't stress enough that the term ecclesial vocation means a vocation that belongs to the Church before it belongs to any individual and that those entrusted with such a vocation are called to serve the whole Church uniquely by modeling or representing the very nature of the Church for all of its members. In fact, because ecclesial vocations are about service rather than self-aggrandizement, those living these vocations can readily recognize that every person is called to holiness and because they serve the Church, they can assist in calling every person to the fullness of holiness in their own vocations.
While the specifically (or explicitly) ecclesial responsibilities of consecrated persons may be greater than those of others in the Church, and while the call to holiness includes the call to model this for others, the call to holiness itself is neither greater nor lesser than the call to holiness of any other person in the Church. Moreover, other vocations are every bit as responsible for the proclamation of the Gospel with their lives, though ordinarily, this means they do so in terms of the secular world in which they live and work and study.One of the problems that cropped up in the wake of Vatican II, in part precisely because of the situation you outlined in your question, was the number of departures from religious life. Because of the universal call to holiness, some felt there was no need to pursue religious life and all it entailed if one could achieve genuine holiness in other vocations. What was necessary was a perspective less geared to an individualistic pursuit of holiness. The focus on the ecclesial nature of vocations to the consecrated state helped the Church find and embrace this new perspective, and it continues to help us hold onto both the importance of consecrated vocations as well as the universal call to holiness and the importance of all other vocations, though perhaps especially, lay vocations. We must not, however, make the same mistake many in the Church once did in treating these vocations as though they represent a "higher (or greater) holiness". Far from moving behind the emphasis of Vatican II, ecclesial vocations to the consecrated state have the mission to serve the Church in specific ways that assist the realization of this universal call to holiness in and by the whole Church.
