[Elsie]

There are countless Protestant sects with important doctrinal differences. How can they possible resolve any doctrinal dispute?

So countless that the 'differences' cannot be named?

[St_Thomas_Aquinas]

What differences? Seriously?

Trinity, transubstantiation, the necessity of baptism, homosexuality, abortion, birth control ordination of women, primacy of Peter, the necessity of Christ's Church, etc., ad infinitum.
