The bishop of Växjö, Sven Thidevall, has called the controversial pastor to a second meeting after the two failed to iron out their grievances at an hour-long meeting in the southern town.
"Apparently we're going to continue our discussion in February," Sandahl told news agency TT after Wednesday's head-to-head with his superior.
The rift between the two men stems from a church summit in October at which Sandahl challenged a female delegate over her expression of support for same-sex marriages.
"Right, so you think that when you fuck somebody you should do it in the ass?" said Sandahl.
Eyebrows were raised at the pastor's outburst, with the bishop immediately slamming his choice of words as undignified and offensive. Sandahl countered that the meeting was of a private nature and that he was accustomed to using language in this way.
"The bishop is trying to use his episcopal power to get me to toe the line," said Sandahl, adding that he had "massive" support from his own congregation on the island of Öland off Sweden's south-east coast.
Bishop Thidevall said Sandahl was at risk of losing the trust conferred on him as a church pastor and confirmed that a second meeting had been scheduled for February.
