We can offer our work in the Mass, achieving a more complete identification with the sacrifice of Christ, and gaining more graces for ourselves and others. This is the most sublime aspect of the Christian spirituality of work, that which makes it a means of holiness. Here is what the Church teaches about this aspect:
Hence the laity, dedicated as they are to Christ and anointed by the Holy Spirit, are marvellously called and prepared so that even richer fruits of the Spirit may be produced in them. For all their works, prayers, and apostolic undertakings, family and married life, daily work, relaxation of mind and body, if they are accomplished in the Spirit--indeed even the hardships of life if patiently born--all these become spiritual sacrifices acceptable to God through Jesus Christ. In the celebration of the Eucharist these may most fittingly be offered to the Father along with the body of the Lord. And so, worshiping everywhere by their holy actions, the laity consecrate the world itself to God, everywhere offering worship by the holiness of their lives. [ftCotCC95, No. 901]
Work also has a social character. When we work with others, a bond is created. This bond is historical (we build open others' shoulders) and temporal (in connection with people throughout the world). Work should create an universal good, that can be shared by all peoples. I think that open source endeavors rightly champion this noble aim. This notwithstanding, we should also recognize the value of property as a means of achieving individual goals. One particular aspect of work, is that it should produce useful goods. We should try that our work creates new possibilities of work for our neighbor. For example, several entrepeneurs are establishing software companies in developing countries.
