 Their charism is “to love the priesthood and to make it loved,” so the apostolates of the sisters predominantly center on assisting priests and promoting the priesthood.These include, but are not limited to, ministering in seminaries, aiding retired priests, sewing vestments, assisting in rectories, working as secretaries for bishops, and conducting religious education in some parishes.The Oblate sisters are also very musical, emphasizing singing and playing instruments during their liturgies and sometimes writing their own music.
