"This Tobin"  clarified his position - 

"On his recent decision to welcome a LGBTQ pilgrimage to the Newark Cathedral, Tobin made clear it was not a prelude to challenging traditional sexual ethics.
“I don’t presume that every person who identifies him or herself as LGBTQ is sexually active,” he said. “If they’re attempting to live a chaste life, then they certainly need the support of the believing community, a chance to pray, and to know that they’re welcomed within the body of Christ.”
The bottom line, according to Tobin, is that “I preach what the Church preaches, and teach what the Church teaches, and believe it with great serenity.” At the same time, he said, “I feel it’s my job to welcome people.”

He is accepting the person - not approving the activity...which is what so many have come to believe for some bizarre reason.
