:Thanks for taking the time to fix this up!  Both of the additions were indeed violations of WP:SYN.  Cardinal Ratzinger's detailed view on the historicity of the gospels is irrelevant to this article.  The material regarding Providentissimus Deus could possibly be rewritten, but as added was a clear violation of WP:SYN due to the manner of its inclusion (e.g., the use of "However").
