 Murphy hoped to produce a balanced depiction of religion, and he, Falchuk and series co-creator Ian Brennan worked to ensure that there was an equality between pro and anti-religious sentiments expressed.The episode features seven cover versions of songs, each of which charted on the "Billboard" Hot 100, marking the series' one-week debut high in the US.Critics disagreed over the appropriateness of the musical performances, with some complaining of the tangential relationship between the numbers and religion, and others appreciating that the "Glee" versions brought new meaning to the songs.
