Plato was definitely not somebody who wasn't to the taste of the Christians. And he can't be meaningfully compared with Sappho, who was obviously seen as a "pure" example of "incompatibility" just like some other antique traditions. Please see my other comments here for the context of the actual writing against female and male homosexuality by the earliest writer, Paul, in the very oldest texts of what later became the New Testament! Read the context there, (although I understand it can be hard as it will probably be greyed, hidden etc. even if these aspects are widely known among the researchers, for centuries) here I just quote:
"Romans 1:26-27 King James Version (KJV)
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet."
Once again, note that this is an older Christian text than the Gospels!
And again, regarding the connection to the Greek philosophy it's the Gospel of John (written later than Paul's Epistles and also later than other Gospels and the Acts) that starts with (in the original Greek) "In the beginning was the Logos, and the Logos was with God, and the Logos was God." (that's the correct translation of John 1:1):

"Despite the conventional translation as 'word'," ["Logos" was] "not used for a word in the grammatical sense; instead, the term lexis (λέξις) was used."
