The forty-fifth anniversary of the formation of the Reformed Congregation of Cluj–Dâmbul Rotund, and the twenty-fifth anniversary of the church construction was in 2005. Just as at the celebration of earlier anniversaries, the church service on 24 April 2005 served for remembrance and reckoning at the same time. Though the population of the congregation had decreased from 2,269 to 1,300, spiritual edification, diaconal work and the education of young people continued. A year earlier, with the help of co-religionists from Heemstede and Haarlem in the Netherlands, the congregation of Dâmbul Rotund had inaugurated a congregation house at Băgara, Cluj county, which served for the spiritual strengthening of the community. During the remembrance there were remembered not only the pastors of the congregation's history and the elders, caretakers and main caretakers, who solicitously loved their church and offered an effective help in the life of the congregation, but also all those, who had participated in the self-empowerment of the congregation and in the construction of the church building, and who, over forty-five years, had served their church by their work, material support and prayers. On the occasion of the anniversary the congregation issued a commemorative booklet with the title “A Kolozsvár–Kerekdombi Református Egyházközség 1960–1980–2005” (The Reformed Congregation of Cluj–Dâmbul Rotund 1960–1980–2005), in which in addition to the construction of the church building they remembered the twenty-five-year history of the choir, and also János Dobri, who played a determining role in the events.
