▼tn After a verb of perception (the participle ὁ πιστεύων [ho pisteuōn]) the ὅτι (hoti) in 5:5 introduces indirect discourse, a declarative or recitative clause giving the content of what the person named by the participle (ὁ πιστεύων) believes: “that Jesus is the Son of God.” As in 4:15, such a confession constitutes a problem for the author’s opponents but not for his readers who are genuine believers.
