Sexual difference plays a pivotal role in Balthasar's thought, as an analogy for the Trinity and as an analogy for the relation between Christ and the church. This essay examines the influence of the analogy of being on his interpretations of these analogies, his understanding of created masculinity, and his use of the language of sexual difference for the Holy Spirit. Ultimately many of Balthasar's best insights about human love as an analogy for divine love can be retained without connecting femininity uniquely with creation, and his trinitarian theology provides the best interpretive key for doing so.
