Resumen:
With the increasing extension of life expectancy, Brazil has become an older country. This implies in more governmental investments for the elderly and a reflection about the demands of this part of the population. In this sense, the theological reflection gains a very important possibility of entering into the debate about the social well being of the elderly guaranteed by legislation with the publication of the Federal Constitution of 1988 and by the complementary law called the Statutes for the Elderly of 2003. This paper is structured in three chapters which are: one dedicated to the comprehension of the elderly, another to understanding the theological referential which considers Public Theology, diakonia and the concept of care, and the last which proposes a reflection about a social project for the rational use of the physical spaces of Pentecostal churches, specifically of the Igreja Ministerial Apostólica Cristã (I.M.A.C.) [Christian Apostolic Ministerial Church], in Patos, in Paraíba.
