本文以台南地區道教二朝以上齋儀演行的〈無上九幽放赦告下真科〉文檢為例，先闡釋文檢中「三天門下」、「泰玄都省」與「風火驛傳」三組詞彙的意涵、來源以及作為仙界公文機關的職能，考論其道經的傳承與轉化六朝至唐代相關政府官署的關係；以具顯道教齋儀放赦文檢得自三天至尊賜赦，三天門下省名義轉頒，泰玄都省負責執行遣發，並召請相關功曹驛吏傳達的程序內涵。其次再探討這七件頒赦文檢的文體意涵，認定三件符命、二份關文與〈赦書〉皆屬下行文，其中「赦書」實質體式應接近「敕牒」功能，而〈放赦九龍榜〉應屬上行「申榜」性質。再者，分析頒赦文檢稱「式」、用印以及批朱、花押與平出的格式特質，以瞭解其與古代公文書的關係，以及正一派靈寶道壇的傳承規矩。
