2. Leave your families:
ἀμὴν λέγω ὑμῖν, οὐδείς ἐστιν ὃς ἀφῆκεν οἰκίαν ἢ ἀδελφοὺς ἢ ἀδελφὰς ἢ πατέρα ἢ μητέρα ἣ γυναῖκα ἢ τέκνα ἢ ἀγροὺς ἕνεκεν ἐμοῦ/ amēn legō hymin, oudeis estin hos aphēken oikian ē adelphous ē adelphas ē patera ē mētera ē gynaika ē tekna ē argous heneken emou
You will notice I bolded the word for wife, as it fits nicely into the reason for this whole thread. However, it is clearly part of a larger picture: the call to discipleship. In other passages, it is clear that this involves leaving possessions, house, and home. However, here what is being singled out is FAMILY. All of the traditional family ties, so vital to social functioning in Jesus day, are less important than his mission.
3. Hate your family:
Mat 10:37 ῾Ο φιλῶν πατέρα ἢ μητέρα ὑπὲρ ἐμὲ οὐκ ἔστι μου ἄξιος· καὶ ὁ φιλῶν υἱὸν ἢ θυγατέρα ὑπὲρ ἐμὲ οὐκ ἔστι μου ἄξιος/ ho philōn patera ē mētera hyper eme ouk esti mou axious ka ho pilōn hion ē thugatera hper eme ouk esti
Lk 14:26: εἴ τις ἔρχεται πρός με καὶ οὐ μισεῖ τὸν πατέρα ἑαυτοῦ καὶ τὴν μητέρα καὶ τὴν γυναῖκα καὶ τὰ τέκνα καὶ τοὺς ἀδελφοὺς καὶ τὰς ἀδελφάς, ἔτι τε καὶ τὴν ἑαυτοῦ ψυχὴν, οὐ δύναται μοι μαθητὴς εἶναί/ ei tis erchetai pros me kai ou misei ton patera heautou kai tēn mētera kai tēn gynaika kai ta tekna kai tous adelphous kai tas adelhpas eti te kai tēn heautou psychën ou dynatai moi mathētēs einai
Thomas 55 (and in 101): [translation from The Complete Gospels] Whoever does not hate fathers and mothers cannot be my disciple, and whoever does not hate brothers and sisters, and carry the cross as I do, will not be worthy of me.
Again, attested to in three sources (and although I would argue that Thomas is dependent on the synoptics, but that Matt/Lk here are not taking from a written Q, most scholars would argue the reverse), we have Jesus hyperbolic denunciation of the family.
4. Let the dead bury the dead:
In Q, (Matt. 8:22/Lk. 59), Jesus is approached by a would-be disciple, who wants to follow, but first needs to attend to his fathers burial. Jesus response: ἄφες τοὺς νεκροὺς θάψαι τοὺς ἑαυτῶν νεκρούς. This response, given the absolutely vital need for a son to make sure the proper burial arrangements of his father were made, would have been absolutely scandalous.
5. Jesus and his own family
Not only do we possess multiple attestations of Jesus denunciation of the traditional family, but the gospels also record tension between Jesus and his own family (which is interesting, and certainly fulfills the criterion of embarrassment). John 7:5 records that Jesus brothers did not believe in him. Mk. 3:21 has Jesus family so concerned they actually think he is mad and are going to restrain him. Mark 3:35 (present also in Matthew and Luke) and Thomas 99 both have Jesus rejecting his family in favor of the true family.
Why all these hostile sayings against families in general and the break between Jesus and his own family? I dont think that Jesus was opposed to families per se. However, part of his mission, I believe, was recreating or restructuring Israel for the kingdom of Yahweh. The old ties of family were superseded by the newer call, just like the old Israel was being redefined in Jesus mission.
Now, I did not do all this to get into a debate about Jesus. One could write several books on this and only scratch the surface. The big names in the historical Jesus quest of late (Crossan, Meier, Wright, and Dunn) have all written more than one book, and Meier recently finished his fourth volume on the subject.
What is important is that it is clearly represented in the Jesus tradition that Jesus teachings undermined how family was understood. This included marriage. Actually, his teachings on divorce, represented not only in the gospels but in our earliest witness (Paul) are ALSO radical. Paul merely forbids divorce (radical enough for that time) while the gospels presume a teaching wherein one man and one woman marry. The important point is that when all this is combined, we get a very clear view that Jesus did not respect the traditional family ties as he was supposed to. He is even quoted as cursing his own community.
In light of all this (combined with the Matthean logion of 19:12, the constant travelling of Jesus with multiple different women, along with no mention anywhere of a wife, and Pauls lack of a reference to Jesus when defending a right to marriage, as well as what appears to be an allusion to the Jesus tradition promoting celibacy) I hardly think it is a stretch to suppose Jesus was a celibate. In fact, I think it very likely, given all of the above.
