This dissertation aims at studying, first, the actuality of Enrique de Ossó´s charism, a lover of human beings and who presents Jesus Christ´s saving proposal. Being not a theologian, his life and writing allow to convey a testimonial theology. In extracts of his Letters, in spite of a dual theological language proper of XIX century, it is noticed the integrating proposal for the human being, from the option for Jesus Christ. When publishing Teresa de Ávila´s writing, Enrique de Ossó presents her as a master and model of somebody who headed her life to Jesus Christ. Second, and in terms of theological consideration itself, with the contribution of some current theologians that study this theme, the aim is to identify briefly the christian biblical integrated anthropology. The christian faith when presents Jesus Christ´s salvation, values the human being in his/her global aspects or dimensions. The current Santa Teresa de Jesus´ Congregation, in its action plans, is in communion with its founder´s beliefs, Enrique de Ossó, continuing formation and education in a unitary view of human being. Finally, some clues for Christian life and pastoral service are presented, aiming at collaborating to overcome anthropologic dualism from Jesus Christ´s salvation as an integrating proposal for human being.
