Mary said to the angel, "How will this be, since I have not had sexual relations with a man?"

For this reason God gave them over to dishonorable passions. For their women exchanged the natural sexual relations for unnatural ones,

and likewise the men also abandoned natural relations with women and were inflamed in their passions for one another. Men committed shameless acts with men and received in themselves the due penalty for their error.
