This text presents a theological and philological reflection on a specific passage from the Gospel of John (14:12), sparked by a conversation between the author and Daniel Blažek, a pastor in Břeclav. The author focuses on Jesus' assertion that those who believe in him will perform "greater works" than those he performed himself. Such a provocative statement is deemed unlikely to be a mere invention of the author, suggesting its roots in an authentic oral tradition that predates the written Gospels. However, the author notes that the phrase "believing in" (using the Greek preposition EN) represents a later theological layer introduced by the early Christian community, as this specific construction did not exist in classical or Koine Greek for the verb PISTEYEIN. The reflection underscores the distinction between original Jesus logia and the subsequent creative piety of the early church. By analyzing these linguistic nuances, the author challenges traditional interpretations and encourages a deeper critical engagement with the Johannine text, highlighting how later additions sought to soften or contextualize radical statements within the Christian tradition.
