March 25th is a day of importance, as well as a historical day, for the following reasons:
1. It is the day of the Annunciation, the day which the archangel Gabriel told Our Lady she was pregnant with Jesus. This happened exactly nine months before the day Christ was born, December 25th. This would be a good thing to bring up to the few who don't think Christ was born on December 25th.
2. March 25th also marked the day of the first Good Friday, the actual day that Christ was nailed to the cross.
3. Last but not least, Archbishop LeFebvre, the founder of the SSPX, passed away on this day.
