This work, which has the title The Other justifying me, this is an exegetical analysis / hermeneutics on the pericope Lucana 18, 9-14, the parable of the Pharisee and the Publican. The methodology is the implementation of the steps of the Critical History Method, also bringing some considerations to the overall reality of theology and some related sciences, such as philosophy and psychology. The parable of Luke 18: 9-14, known as the Pharisee and the Publican, throughout history has been interpreted as a parable that deals on prayer, that is the proper way in which the student must refer to God. Another recurring line throughout history is that this was a parable about humility, as the superb attitude of the Pharisee contrasts with the humble figure of published that dares not even raise his eyes to heaven, and down home receiving the divine favors. This study continues to show the validity of these interpretations, at the same time shows that they are not enough to display the text meaning of wealth. This paper aims to explain the parable as an example already present in the synoptic of the doctrine of justification by faith, which will be further developed by the apostle Paul, and that includes most all the semantic meaning of this, and that also includes previous interpretations They were made from this.
