This article presents the dynamics of formation and expansion of Radiofonics Schools of ACPO in the parishes of Pamplona, in the department of Norte de Santander, in its founding phase took place between 1954 and 1957. ACPO was a priestly initiative of Father Salcedo gradually transformed into a work of the Church guided by the current of social Catholicism who proposed the literacy, evangelism and spreading the Fundamental Integral Education within the rural population through a combined system media. It is proposed that in the beginning, the expansion of EE.RR was made possible by the support church, for the support of departmental governments under national policies and forcibly acquired by the figure of the pastor in the rural population. In this sense, we propose that the EE.RR been a center of cultural propagation but also Catholic Action space used by the church hierarchy to Christianize and prevent adverse influence of political ideas through education and culture. keywords: Popular Cultural Action, Sutatenza Radio, radiophonic school, social Catholicism, parishes, archdiocese of Pamplona.
