Go and make disciples of all nations!

"It would be useful if every Christian and every evangelizer were to pray about the following thought: men can gain salvation also in other ways, by God's mercy, even though we do not preach the Gospel to them; but as for us, can we gain salvation if through negligence or fear or shame- what St. Paul called "blushing for the Gospel" - or as a result of false ideas we fail to preach it?" from Paul VI, Evangelii Nuntiandi
