Gospel was given to the Church of Christ at the time of His earthly sojourn, death and resurrection and through sending of the Holy Spirit during the Pentecost.
The holy books and passages were written AFTER the Gospel was given. So the Books of New Testament are based on the Gospel and Gospel is not based on them. The pillar and ground of Truth is the Church (1Tm:3:15). The Church wrote, selected and canonized the Scriptures under inspiration of Holy Spirit, first were the Apostles and then there were the books of New Testament, first were the patriarchs and prophets and then there were the books of Old Testament.
We agree. How about we continue from this agreement and talk about what the Teachings tell us about commerce.

What ever we do, let's agree on the Truth and move forward together..
