1 tn The mutual interrelationship of the Father and the Son (ἐγὼ ἐν τῷ πατρὶ καὶ ὁ πατὴρ ἐν ἐμοί ἐστιν, egw en tw patri kai Jo pathr en emoi estin) is something that Jesus expected even his opponents to recognize (cf. John 10:38). The question Jesus asks of Philip (οὐ πιστεύεις, ou pisteuei") expects the answer “yes.” Note that the following statement is addressed to all the disciples, however, because the plural pronoun (ὑμῖν, Jumin) is used. Jesus says that his teaching (the words he spoke to them all) did not originate from himself, but the Father, who permanently remains (μένων, menwn) in relationship with Jesus, performs his works. One would have expected “speaks his words” here rather than “performs his works”; many of the church fathers (e.g., Augustine and Chrysostom) identified the two by saying that Jesus’ words were works. But there is an implicit contrast in the next verse between words and works, and v. 12 seems to demand that the works are real works, not just words. It is probably best to see the two terms as related but not identical; there is a progression in the idea here. Both Jesus’ words (recall the Samaritans’ response in John 4:42) and Jesus’ works are revelatory of who he is, but as the next verse indicates, works have greater confirmatory power than words.
2 tn Grk “I do not speak from myself.”
3 tn Or “does.”
4 tn Or “his mighty acts”; Grk “his works.”
sn Miraculous deeds is most likely a reference to the miraculous signs Jesus had performed, which he viewed as a manifestation of the mighty acts of God. Those he performed in the presence of the disciples served as a basis for faith (although a secondary basis to their personal relationship to him; see the following verse).
5 tn Grk “but he said to them.”
6 tn Or “marks.”
7 tn The word “it” is not in the Greek text but is implied. Direct objects were often omitted in Greek when clear from the context. The use of “it” here as direct object of the verb πιστεύσω (pisteusw) specifies exactly what Thomas was refusing to believe: that Jesus had risen from the dead, as reported by his fellow disciples. Otherwise the English reader may be left with the impression Thomas was refusing to “believe in” Jesus, or “believe Jesus to be the Christ.” The dramatic tension in this narrative is heightened when Thomas, on seeing for himself the risen Christ, believes more than just the resurrection (see John 20:28).
