Then, in September 1888 he married a young Orthodox lady, Harita Hiroko Uematsu, With his abilities with the Russian language and his status as a ''Magistrant'' alumnus of the Kiev Academy, Simeon was name, in the spring of 1891, as part of the four man delegation from the Japanese Orthodox Mission for the formal farewell ceremony for the Russian Crown Prince, the future Czar Nicholas II, after his visit to Japan.
In March 1893, after the couple lost their first-born son Alexander, Simeon chose to enter the [[clergy]]. He was [[
ordain]] ed a [[deacon]] by Bp. Nicholas in January 1894, and then a [[priest]] one month later in February. With his high intellectual ability and advanced education, Fr. Simeon rose rapidly. In addition to his clerical duties Fr. Simeon became the publisher-of-record of the new Japanese Orthodox theological journal ''Shinkai'' (Divine Sea), holding this position for the next six years.
For his first [[parish]] Bp. Nicholas assigned Fr. Simeon to the church in Kyoto, an important Japanese cultural center and former imperial capital, with additional duties of making periodic pastoral visits to missions in western Honshu. As his parish grew he found a need for a larger church building. Receiving Bp. Nicholas’ approval he managed the construction of the '''Church of the Annunciation''' as a building worthy of the the cultural importance of its location in Kyoto. Construction of the church began in late 1898 and was [[consecrate]]d in May 1903. The [[iconostasis]] and bell were donated by Russian citizens. Also, presented to the new church was a [[Gospel]] inscribed with a greeting by Fr. [[John of Kronstadt]].
