These two sects believe outside the 24 inspired and infallible prophets in the 66 books of the bible, some mortals exhibit the same traits. For SDAs, it is just one woman, their godess, Ellen White while for Catholics,it is the popes. A catholic will swear that they believe in scriptures not men but their beliefs are carefully filtered through Rome. The can't afford to differ with Papal Rome. An SDA on the other hand may spew tons of verses, but they dread opposing Ellen White. That is regarded as a damnable heresy. SDAs are just a different shade of Catholicism. Little wonder then that like David's indignation in 2Samuel 12, they are really angry at themselves!
