The true church must have the same organization as Christ's church. Paul says first in line come the apostles, next the prophets. Mormonism reverses this order. The true church must claim divine authority. Again, this is purely subjective.
Any organization can claim to be authoritative.
Bible-believing Christians claim the authority of God's Word, the Bible, not the words of mere men who contradict it. The true church must have no paid ministry. Mormons who believe their leaders are not paid are very misinformed. All the General Authorities in Salt Lake City receive remuneration for their services to the church and from the church. If they don't believe it, they should call the LDS Church headquarters and ask.
