Ryōyo Shōgyō 了譽聖冏 (Reki’ō 4 / 1341 – Ōei 27 / 9 / 27 = 1420-11-02), Nanboku-chō → early-Muromachi Jōdoshū master, the seventh patriarch (七祖) of the Chinzei-line and the architect of the Chinzei-line scholasticism that became the institutional foundation of medieval and early-modern Jōdoshū doctrinal training. Lay surname Saitō 齋藤; native of Iwasebori in Hitachi 常陸 province (modern Ibaraki). Hieizan ordination in his youth before transferring to the Chinzei-line at Bansei-ji 萬歳寺 under Shōgyōbō of the Shiroho-ha 白旗派. Later abbot of Daijō-ji 大乘寺 in Shimōsa and of Renkō-ji 蓮光寺 in Iwasaki, and the founder of Denzū-in 傳通院 in Edo (one of the future Tokugawa-period principal Jōdoshū institutions).
Shōgyō is the principal scholastic systematizer of the Chinzei tradition: he is responsible for the Goji hachiyaku 五時八益 doctrinal scheme (the classification of Jōdoshū teaching into five periods and eight benefits, modelled on Tendai’s Goji-hakkyō but adapted to Pure-Land) and the Shōkō Shoshi-ha 聖光諸子派 historical-doctrinal taxonomy of the post-Hōnen schools. His principal works include:
- Jōdo nizō nikyō ryakuju 淨土二藏二教略頌 (KR6t0320) — verse digest of the Two-Stores Two-Teachings classification;
- Jōdo hōmon genrushō 淨土法門源流章 — historical-doctrinal genealogy of all post-Hōnen Pure-Land lineages (parent text of the Shōkō Shoshi-ha taxonomy);
- Denzū-in shōki 傳通院章記 and Senchaku denkō ketsugi-shō chū 選擇傳弘決疑鈔註 (a sub-commentary on Ryōchū’s Ketsugi-shō KR6t0316 — making Shōgyō the third generation of Chinzei Senchakushū scholasticism);
- several catechisms and Sanji ritual texts.
Shōgyō’s principal disciple was Yūyo Shōso 酉誉聖聰 (1366–1440), eighth Chinzei patriarch and founder of Zōjō-ji 増上寺 in Edo (the Tokugawa-clan tutelary temple). The Chinzei-line institutional dominance of Jōdoshū in the Edo period is largely a consequence of Shōgyō’s Kantō expansion and his Goji-hachiyaku doctrinal codification. Wikidata Q11581849.
