But are you reading them objectively?
I don’t know whether anyone can completely divest one’s self of their spiritual leanings. However I do search out wisdom and spiritual truths from sources other than LDS. There are many LDS that earnestly search out and study such material, not to try and poke holes in someone’s belief but to gain insight, and benefit from some wisdom that might be imparted. We may not accept the creeds and beliefs of others, but that is not say that there is nothing to be learned.
Are you reading them from a Catholic perspective, wanting to believe that they support catholic doctrine?
When I read, I try not to view the writing as Catholic or Protestant, but as from people who themselves were earnestly seeking the ways of our Savior to the best of their knowledge. As I read some things ring familiar to me, some don’t, and there are others that can be interpreted in equally valid ways depending on your doctrinal view. Not that there can be two truths, but enough vagueness in wording appears so that opposing claims can be made.
Or are you viewing them through the lens of LDS doctrine hoping to find additional “proof” of the divinity of Joseph Smiths church?
I do not have to search for proof I have the wittiness of the Holy Ghost to my spirit as to the office our Father in Heaven granted Joseph Smith.
I would like for you to reference which specific writings that you felt contained doctrinal ideas that were closer to LDS views than Catholic. (even better if you could explain why you came to this conclusion)
I was reading St. Irenaeus “The Demonstration of Apostolic Preaching” paragraph 9
*9. Now this world is encompassed by seven heavens in which dwell powers and angels and and angels and archangels, doing service to God, the Almighty and Maker of all things: not as though He was in need, but that they may not be idle and unprofitable and ineffectual. Wherefore also the Spirit of God is manifold in (His) indwelling, and in seven forms of service is He reckoned by the prophet Isaiah, as resting on the Son of God, that is the Word, in His coming as man. The Spirit of God, he says, shall rest upon him, the Spirit of wisdom and of understanding, the Spirit of counsel and of might, (the Spirit of knowledge) and of godliness; the Spirit of the fear of God shall fill him. Now the heaven which is first from above, and encompasses the rest, is (that of) wisdom; and the second from it, of understanding; and the third, of counsel; and the fourth, reckoned from above, (is that) of might; and the fifth, of knowledge; and the sixth, of godliness; and the seventh, this firmament of ours, is full of the fear of that Spirit which gives light to the heavens. For, as the pattern (of this), Moses received the seven-branched candlestick, that shined continually in the holy place; for as a pattern of the heavens he received this service, according to that which the Word spake unto him: Thou shalt make (it) according to all the pattern of the things which thou hast seen in the mount. *
Although it is not the same in description as LDS have it, this passage does describes different levels in the economy of our Father in Heaven which indeed has a familiar ring to me.
