Relics, Aliens, and the Bible (encore)

Is there a biblical basis for relics? Is asking for the intercession of the saints like necromancy? What is the Douay–Rheims Bible? If aliens exist, how would that affect the Catholic faith? How can heaven be perfect if our loved ones are not there? Are the biblical manuscripts reliable? Cale hosts an ‘Ask Me Anything’ session. You can email questions to Cale here: cale@relevantradio.com.
