The Priestly Society of St Peter (FSSP) has, on average, been ordaining about 11 new priests each year, and has thus experienced steady growth. It currently has 262 priests. 2015 was a good year for ordinations with 15 new priests, and 2016 is also looking good with 14 ordinations expected. However, if all goes well, 2017 will be a record breaking year with 24 ordinations.
That amounts to 53 ordinations in three years, or an increase in the size of the order of over 20%.
I understand that ten young men from England and Wales are currently studying at FSSP seminaries ,so we can expect that England and Wales will benefit from the growth of the FSSP.
