10. Equivalent collegial actions cannot be carried out at the level of individual particular Churches or of gatherings of such Churches called together by their respective Bishops. At the level of an individual Church, it is in the name of the Lord that the diocesan Bishop leads the flock entrusted to him, and he does so as the proper, ordinary and immediate Pastor. His actions are strictly personal, not collegial, even when he has a sense of being in communion. Moreover, although he has the fullness of the power of the Sacrament of Orders, he does not exercise the supreme power which belongs to the Roman Pontiff and to the College of Bishops as elements proper to the universal Church, elements present within each particular Church in order that it may fully be Church, that is, a particular presence of the universal Church with all the essential elements pertaining thereto.(⁴⁶)

At the level of particular Churches grouped together by geographic areas (by countries, regions, etc.), the Bishops in charge do not exercise pastoral care jointly with collegial acts equal to those of the College of Bishops.
