Father Shaun O'Connor: Why affiliate Saint Mary's Church in Orange with a Church that promotes homosexuality?

The New England Conference of the United Methodist Church is very pro-LGBT.  See here. This goes for the South Athol United Methodist Church and its "pastor" Judy Jones.

As noted in The Athol Daily News, see here:

"The South Athol United Methodist Church is a Reconciling Church, meaning it is inclusive of all sexual orientations and gender identities. Zane Dubour, a member of the church’s administrative council, said the 3-by-5-foot rainbow-striped flag is a statement and acceptance of homosexuality...

South Athol United Methodist Church pastor Judy Jones, according to the statement, said the global church’s discriminatory stance against gay and lesbian pastors is not reflective of the general opinion of the members within many United States churches, while the New England Conference of the United Methodist Church stands in distinct non-conformance."

Which makes it all the more troubling that Saint Mary's Church in Orange, with the blessing of Father Shaun O'Connor, is engaging in Bible Studies with this Methodist Church and its pro-homosexual "pastor."

In an Instruction entitled "Some Considerations Concerning The Response To Legislative Proposals On The Non-Discrimination Of Homosexual Persons," issued on July 22, 1992, the CDF had this to say: "'Sexual orientation' does not constitute a quality comparable to race, ethnic background, etc. in respect to non-discrimination. Unlike these, homosexual orientation is an objective disorder and evokes moral concern." (No. 10).

And again: "Including 'homosexual orientation' among the considerations on the basis of which it is illegal to discriminate can easily lead to regarding homosexuality as a positive source of human rights, for example, in respect to so-called affirmative action or preferential treatment in hiring practices. This is all the more deleterious since there is no right to homosexuality which therefore should not form the basis for judicial claims. The passage from the recognition of homosexuality as a factor on which basis it is illegal to discriminate can easily lead, if not automatically, to the legislative protection and promotion of homosexuality. A person's homosexuality would be invoked in opposition to alleged discrimination, and thus the exercise of rights would be defended precisely via the affirmation of the homosexual condition instead of in terms of a violation of basic human rights." (No. 13).

This is the position of the Catholic Church, founded by the Lord Jesus.  Does Father Shaun accept this teaching?  And what is the purpose of conducting Bible Studies with those who reject the teaching of Sacred Scripture with regard to homosexual acts?

Should a Catholic priest affiliate himself, and the parish he is supposed to lead, with a Protestant Church which rejects the inerrant Word of God and what the Holy Spirit has to say about that sin which cries to Heaven for vengeance?  See here.
