That doesn't explain Mark 7 and your out of context citation. No single Scriptural principle can be adequately conveyed with a single verse.
The Word of God is a tapestry of interdependent and interrelated thoughts. No single thread or source of light does it justice. The catholic Mass recognizes this and provides an Old Testament verse, a New Testament verse and a quotation from Christ Himself and follows it up with a homily tying them together and elaborating on the concept. The Protestant practice of using single out of context versus as factoids and sound bites to support their Scriptural assertions is about as disingenuous as an Obama campaign commercial.
Tell us oh mighty one - which tradition was He not addressing.
Would that be like taking John 6:53-56 53 Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in them.
literally, but not taking John 6:28-29 Then they asked him, “What must we do to do the works God requires?” 29 Jesus answered, “The work of God is this: to believe in the one he has sent.” Literally?
And there are a multitude of other passages in Scripture where Catholics demand a literal reading of Scripture to back up their doctrine, and else where insist that it's figurative, and in even other places, deny Scripture entirely and use *TRADITION* to trump Scripture.
You're in a poor position to make that complaint against others.
