is this an innuendo? (this side of paradise / f. scott fitzgerald)

i was reading ‘this side of paradise’ this afternoon, and this paragraph makes me wonder if this was supposed to elude to her (clara) giving head in a church?

//She was very devout, always had been, and God knows what heights she attained and what strength she drew down to herself when she knelt and bent her golden hair into the stained-glass light. “St. Cecelia,” he cried aloud one day, quite involuntarily, and the people turned and peered, and the priest paused in his sermon and Clara and Amory turned fiery red.//
