There are emerging certain tendencies aiming at the establishment of smaller communities. A sort of spontaneous reaction against the anonymity of the great urban centers, the necessity of adapting the living quarters of a community to the cramped environment of modern cities and the very need to be closer, in one's living conditions, to the people to be evangelized -- these are among the reasons that lead certain institutes to plan by preference the foundation of communities with a small number of members. Such small communities can in addition favor the development of closer relationships between the religious and a shared and more fraternal undertaking of responsibility. Nevertheless, while a certain structure can in fact favor the creation of a spiritual environment, it would be vain to imagine that it is sufficient for making it develop. Small communities, instead of offering an easier form of life, prove on the contrary to make greater demand on their members.On the other hand it remains true that communities containing many members particularly suit many religious. Communities of this sort may likewise be called for by the nature of a charitable service, by certain tasks of an intellectual nature or by the contemplative or monastic life. May perfect unity of hearts and minds be always found there, in exact correspondence to the spiritual and supernatural goal which is pursued. Besides, whatever their size, communities large or small will not succeed in helping their members unless they are constantly animated by the Gospel spirit, nourished by prayer and distinguished by generous mortification of the old man, by the discipline necessary for forming the new man and by the fruitfulness of the sacrifice of the Cross.
