On MONDAY, JANUARY 5, Vigil of the feast of Epiphany, after the Low Mass at noon, there will be a special blessing of Epiphany Holy Water. You are invited to bring water to receive this powerful and solemn blessing, in order that this water may be used in your homes and for the sick.
I kindly request you to bring no more than two water containers per household, and the containers must not be smaller than one gallon. And also put your names and telephone numbers on your bottles. So many were not claimed last year.
Thank you for your understanding.
Sincerely yours in Christ
Canon Ueda
