That's a big title. But Christians are here to do big things. For with God, nothing is impossible (Lk 1:37).
So how do we renew the world? By renewing the Church.
And how do we renew the Church?
The solution comes from the greatest analyzer of present-day affairs: Pope Ratzinger.
To a great extent, the renewal of the Church throughout the world depends on the renewal of the practice of Penance and the growth in holiness which that sacrament both inspires and accomplishes.
The liberating power of this sacrament needs to be rediscovered and owned once again by every Catholic.
Let's start in our beloved Catholic country: let each Filipino Catholic rediscover the liberating power of Confession, so we can renew the Church and the world. That's our mission.
To help in this renewal, you might want to take a look at this powerpoint on Sin and Confession: How to renew the Church and the world.
