An objective evaluation of both Old and New Testaments will reveal that the authors, building and enlarging upon the expectations of their predecessors, worked in sequence towards an ultimate goal - the establishment of an ideal kingdom - the Kingdom of God on earth.
It was only after many years of bitter controversies that the Triad of 'mystery' doctrines - Trinity, Miraculous Incarnation and Transubstantiation - came to be regarded as 'truths' necessary for salvation.
In reality, they serve no other purpose than to confuse the issues and to make appreciation of the 'kingdom' plan impossible.
That these 'mysteries' have their origins in sources far removed from the bible should be obvious to any student of ancient history.
An exhortation of the New Testament is to "Prove all things; hold fast to that which is good." (I Thess 5:21). A wise injunction - one to which I subscribe. One which will form the basis of our examination of church doctrines.
Most reasonable people would reject the notion that all is hidden in 'mystery'. If they are followers of Jesus of Nazareth, they are quite entitled to expect that there is nothing hidden that shall not be revealed. (Luke 8:17)
