Here is what I believe on those, after my research:
1. 1914 > Speculation, one of the deceptions
2. Blood policy > as other things, has Masonic connection (see Springmeier's books)
3. The position of Jesus > The way, the truth, the life. Acts 4:12. Jesus prayed to his (and our) heavenly Father, but interestingly never used/pronounced his name. Jesus has full authority (Mt 28:18). We cannot bypass Jesus to be acceptable before God.
And one more important thing I've forgot:
I now believe and realize that Christians must partake emblems as instructed by Jesus, either privately or publicly (shouldn't matter).
