Every year brothers assembled for one or several “conventions,” most being held in Kristiania. At the beginning, the conventions in Norway usually were arranged in connection with visits by traveling representatives of the Society. Prior to 1920 few Norwegian brothers were capable of speaking at the assemblies. Therefore, most of the talks were given by foreign brothers, especially Swedish and Danish. The last part of the program usually was a “symposium,” several brothers giving short talks on different aspects of a certain subject. These talks often were given by less experienced brothers, who thus got some practice. From about 1920 onward, Norwegian brothers gave most of the talks at the assemblies.

Yet, quite a few young people were becoming part of the congregation. At an assembly in Kristiania in 1924 about twenty-five new brothers and sisters were baptized, a large number at that time. In the years thereafter, this joyous occasion was spoken of as “the grand baptism.”
