QUINCY -- Known in past years as the 'Night 4 Life,' the Daughters of Mary of Nazareth and Men of Divine Mercy Prayer Group organized a slightly different event this year. Billed as 'A Weekend 4 Life,' it included two events: a Mass with Cardinal Seán P. O'Malley on Sept. 30, and a prayerful gathering at the Marriott Boston Quincy on Oct. 1.
