 Bultmann had visited Uppsala shortly after Fridrichsen and Giertz had returned from Palestine, a trip Bo’s father had paid for, and which Giertz later described as part of the setting for his 1948 book "Med egna ögon" ("With My Own Eyes").According to Giertz, Rudolf Bultmann treated Christianity as a philosophical system rather than a lived experience, and could not, therefore, appreciate Fridrichsen's explanation of how visiting Palestine and seeing people living and working much as they had during the earthly ministry of Jesus had deepened his understanding of scriptures and Christianity.After completing seminary training, Giertz spent three years as a travelling consultant for the Lutheran church’s high school student association.
