Tea followers were among the earliest converts to the Christian faith. Takayama Ukon, a daimyo turned ardent evangelist, was a disciple of Sen no Rikyu, the preeminent tea master of all time. After Christianity had been banned - Takayama was exiled to the Philippines - underground Christians cherished the tea ceremony as the only opportunity to assemble without arousing suspicion on the part of the authorities. It proved to be a fitting substitute for Holy Communion; even in its Zen context the rite symbolized the giving of oneself. For Christians liable to detection and torture because of their outlawed faith, it was a solemn reminder that Christ had willingly given his life for them. Some of the cups were boldly inscribed with a cross. So it is little wonder that some Japanese Christians have envisioned their Lord in the graceful robe of a Zen tea master.
