On Sunday we considered the Scripture's stern warning to watch out for those who twist or deny the gospel. The Episcopal Church USA (and its presiding bishop Katherine Jefferts Schori) is a perfect example of this. See some discussion of this here.
To write the same things to you is no trouble to me and is safe for you. Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. For we are the real circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh... (Philippians 3:2-3, ESV).
