St. Boniface is one of those I try to remember each year on their feast day. His feast day is June 5. This year, I will simply link to the Holy Father's catechesis on St. Boniface from the General Audience of March 11, 2009.
Here is part of that catechesis:
"By comparing his ardent faith, this zeal for the Gospel, with our own often lukewarm and bureaucratized faith, we see what we must do and how to renew our faith, in order to give the precious pearl of the Gospel as a gift to our time."
