The internal structure of the Church
Re: communion of the believers:
“Since the communion between believers consists in both giving and receiving, their interior communion will entail both sides of this exchange. They give of their merits, prayers, and suffrages before God as intercession and aid for the benefit of others. They receive by the help of others gifts of grace and increase of grace, and the protection of God sheltering them from evil and increasing the good things in their lives. There is a twofold cause at the origin of these spiritual aids. At times they arise directly from an individual’s loving concern, as when a person living in charity prays according to his individual intention on another’s behalf, or does a good work or some penance for this person, and so obtains for him the gift of grace, increase of grace, protection against temptation, or the like. But at other times help is given by way of an institution, or action of the Church, as when by masses and by other official forms of worship people are helped toward doing good or avoiding evil.” (Cajetan 2011, 92)
This goes towards the positive work one expects of a member of the Church, as a member. Individual good works and personal prayer are a constituent part of the treasury of grace in the Church.
“Hence, concerning what a person receives there is no fundamental difference between the interior communion of direct sharing in love and the interior communion by way of the action and institution of the Church.” (Cajetan 2011, 93)
In general, Cajetan’s discussion on excommunication (see Cajetan 2011, pp 94-95) is interesting for insisting on the connection between external membership in the Church and internal graces.
