 , the video is in and of itself a promotional item made for the purpose of reaching a large audience, which it has.  Accordingly, this is a primary source which has been reliably published (by the church).  It contains Flowers' own words about his religiosity and therefore not an independent third party as well as no analysis, synthesis, interpretation, or evaluation of the material is given.  The article states simply that he was ""featured on the church's website in a promotional video"".  I see no need for a secondary source.  Also, the secondary source you provided takes aim at the church's political position on same-sex marriage which does not perhaps reflect the best views of Mr. Flowers, since there is no mention of his views personally.
