The first festal all-night vigil in honor of Elder Iakovos Tsalikes took place from the 17th to the 18th of November 2017, ten days before he was officially recognized as a Saint by the Ecumenical Patriarchate. This was done by Metropolitan Neophytos of Morphou in the Church of Saints Barnabas and Hilarion in the village of Peristeronas in Morphou, Cyprus. The Service to Elder Iakovos had been composed by Nun Isidora of the Monastery of Saint John the Forerunner in Makrynos which is in Megara, with additions from a Service composed by Metropolitan Joel of Edessa.
This was done to honor Elder Iakovos on the anniversary of his repose, which took place on November 21, 1991. Though unaware of the coming official recognition of Elder Iakovos as a Saint of the Church, this can be seen as being done in anticipation of the event. Metropolitan Neophytos had known Elder Iakovos while alive since his student days, and simply wished to honor the man who in the conscience of the faithful was already a Saint of the Church, to whom icons had been painted and hymns composed, and whose miracles are known throughout the world.
Below are videos from the vigil, which includes a 30-minute reading of his life:
