I use that term to refer to the great number of myths about what the Bible teaches that are believed today as the truth by the majority of people that call themselves Christians.
I am IN CHRIST and am still not a sheep. Once again, God refers only to Israel as His sheep in the Bible. I am a part of His body.
I am a body part and not a sheep. There is a significant difference between the doctrines that Paul teaches regarding His body and and what Jesus taught His sheep.
Please note the difference here as an example:
Matt 6:14-15 (AKJV/PCE)
(6:14) For if ye forgive men their trespasses, your heavenly Father will also forgive you: (6:15) But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Eph 4:32 (AKJV/PCE)
(4:32) And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
One clearly is different than the other.
