El Clérigo is a character in 'Lazarillo de Tormes' who represents the hypocrisy and moral corruption of the clergy during the Spanish Golden Age. He is portrayed as a man who, despite holding a religious position, is more concerned with material wealth than spiritual well-being, illustrating the theme of social criticism present in the work. His actions and attitudes reveal the broader critique of religious figures and their failure to uphold the values they are supposed to represent.
