I keep hearing ministers express the irrelevance of the Old Covenant (Old Testament/Law) as if we can toss everything prior to Matthew's gospel from the Canon of Scripture. Ironically, even though we know the New Testament is inspired and serves as Scripture illuminating the New Covenant, there is no clear reference by many of the New Testament authors confirming that they intended their writings to be such. Contrast that with numerous instances where these same authors reference the OT; refering to it as Scripture.
How do we in good conscience condemn everything OT? Tithing pre-dates the Law, but we say it's no longer relevant because it's in the OT. What about the 10 Commandments that is the cornerstone of the OT Law? Do we toss that also? Why also do many 'New Testament' churches decommission significant NT rites such as water baptism and communion? And, in light of our loose nature concerning Christian observances, why do we complain when people opt to conserve finances by 'churching at home' via television or the web?
