No one is forced to be a Christian. But no one should be forced to live according to the "new religion" as though it alone were definitive and obligatory for all mankind.
To live without faith, without a patrimony to defend, without a steady struggle for truth – that is not living, but existing.
“If you believe what you like in the Gospels, and reject what you don’t like, it is not the Gospel you believe, but yourself.”
Those who with God's help have welcomed Christ's call and freely responded to it are urged on by love of Christ to proclaim the Good News everywhere in the world.
The Eucharist is "the source and summit of the Christian life."
An unusually good entry on the Catholic Herald entitled "Why Catholics should defend indulgences" gives a good account on indulgences.
It is a very good explanation on why they are a good that should not only be defended but promoted, and shows that it is entirely in line with Christian apostolic tradition.
