Porsha Williams' Evangelist Past Hits the Web! Video Rant LEAKS About How SHE HATES GAYS!

Before Porsha Williams thumped Kenya Moore, she thumped bibles -- ranting from the pulpit about gays and lesbians destined for an eternity in hell.

Video shot roughly 3 years ago at High Praise Christian Center Ministries in GA has just surfaced, showing Porsha preaching and rambling about saving hookers, drug dealers, people who attempt suicide ... and gays and lesbians.

She screams, "We're supposed to try and save them and tell them, ‘You are worthy!'" She doesn't stop there either ... you gotta see this.

We reached out to Porsha for comment -- so far, no word back.
