The text of Ml 1,6-14 is a prophetic critique of the second Temple. The prophet presents his critique of the priests who offer animals unfit for YHWH and also the justification of the same critique, presented in vv. 11 and 14d-f. This dissertation aims to verify in detail the meaning of prophetic criticism and particularly establish the meaning of Ml 1,11, since the interpretation of this verse is cause of great disagreement among scholars. It is objective, yet, this dissertation study the theological aspect of the justification of prophetic critique of the cult found in Ml 1,11 and 14d-f. To achieve this goal the search begins with the translation of the text, its delimitation and placement throughout the book of Malachi. After addresses the organization of the text, its unity, dating and literary genre, in the third chapter is made the comment about the vv. 6-10.12-14a-c. The vv. 11 and 14d-f are discussed in a separate chapter, which is devoted greater attention to v. 11, establishing, first, the status quaestionis of his interpretation, since the late Judaism until the present time. The last chapter discusses the theological background of the prophetic critique and the relationship between Ml 1,6-14 and Nm 6,23-27. This study concludes that the prophetic critique of Ml 1,6-14 reveals contact points with Nm 6,23-27, being a kind of anti-blessing with which priests and people (Ml 1,14) are convicted of not doing the worship YHWH in its proper form and with proper interior disposition. It also shows that to understand the real meaning of v. 11 it is necessary to read it along with the v. 14d-f, taking into account the theology of the name of YHWH and YHWH s image as king that underlie the text as a whole.
