This article analyses how themes and problematisations concerning social justice presented in a pre-service English language teacher education programme in São Paulo, Brazil, resonate in student teachers' knowledge production processes. To do so, the case study is presented in two parts. The first one examines the theoretical foundations and the organisation of two specific courses on language teaching methodology, courses whose epistemological approach aligns with decoloniality and narrative documentation of learning experiences. In the second part, essays produced by student teachers enrolled in these courses are analysed thematically to discuss evidence of how the course resonates on student teachers' knowledge of more culturally sensitive and socially relevant educational principles and practices. This double-folded analysis reveals the transversality of social justice principles and practices in student teachers' process of becoming English language teachers and language educators with a sense of belonging to all-embracing commitments of the profession.
