Resumen:
When approaching the study of theological treatises in Christianity, the affirmation of the Trinity as the center and particularity of the Christian God, who is understood as One and Triune, is recurrent. Yet, it must also be recognized that not all the Persons of the Trinity are equally studied, contemplated, preached, or mentioned. Recognizing this paradigm, the objective of this investigation is the systematization of pneumatology in the history of Western theology. Although the objective is the systematization of pneumatology, the investigation has as its specificity the search for the feminine of the Holy Spirit. This search for the feminine of the Holy Spirit is guided by feminist theology which, with its biblical hermeneutics, reaffirms the feminine when speaking of the divinity. The research addresses the theology about the Third Person of the Trinity in the Ancient and Middle Ages, especially checking the silences or affirmations of the feminine of the Spirit. Finally, Martin Luther's pneumatology is approached, seeking to distinguish the originality of his theology about the Holy Spirit and whether or not there is a forgetfulness regarding the feminine of the Holy Spirit.
