Spreading the Gospel by being saints
There was to be nothing special about it, nothing that savored of a religious Order, no special rule, no distinctive habit. She, and those who joined her, would simply be poor--there was no choice on that score, for they were that already--but they would embrace their poverty, and the life of the proletariat in all its misery and insecurity and dead, drab monotony. They would live and work in the slums, lose themselves, in the huge anonymous mass of the forgotten and the derelict, for the only purpose of living the complete, integral Christian life in that environment--loving those around them, sacrificing themselves for those around them, and spreading the Gospel and the truth of Christ most of all by being saints, by living in union with Him, by being full of His Holy Ghost, His charity.
