Just to be clear: You are not obligated to fast today. Only on Ash Wednesday and Good Friday. Abstinence on the other Fridays.
Our parish has grown from a few hundred families to 7,000+ over the past 20 years (St. Ann in Coppell). We're now the largest parish in Dallas, and the sixth largest in the country.
Sounds great, but to tell you the truth, only about a third regularly attend Mass. If it was 100%, we'd need ten more Masses on Sunday. It's a very active parish with dozens of ministries.
