The entrance of Camilo Torres Restrepo to the National Liberation Army (ELN), supposed the alliance between two visions that were considered antagonistic in a guerrilla organization: Marxism and Christianity. Based on a qualitative study, this research aims to analyze the union between Marxism and Christianity in the ELN in the period from 1986 to 1989. It is argued that the union is mediated by the symbolism created around the figure of Camilo Torres that it manifested itself in the promotion of a possible, and even obligatory, link between Christians and Marxists in the guerrilla organization in the late 1980s.
