You can perform your ceremony according to the buddhist rites. Buddhist wedding is a mutual commitment between bride and groom, officiated during a ritual blessing ceremony, rather than a sacrament. Thou being conventionally recognized by the community, the bond has no legal value. It has to be confirmed by civil marriage according to the Italian law. The ceremony will be open by the reading of Hoben chapter and of Jgage, followed by some Daimoku moments. Bride and groom, together with their witnesses, will drink three sips of sakè from three cups, symbolizing past, present and future. Guests will freely express their emotions and will cheer. The reading of three Daimoku will end the ceremony.
