There were many things NOT in scripture by which the ancient Church had to make authoritative pronouncements.
Acts. 15.28-31:
28 'It is the decision of the holy Spirit and of us not to place on you any burden beyond these necessities, 29 namely, to abstain from meat sacrificed to idols, from blood, from meats of strangled animals, and from unlawful marriage. If you keep free of these, you will be doing what is right. Farewell.'" 30 And so they were sent on their journey. Upon their arrival in Antioch they called the assembly together and delivered the letter. 31 When the people read it, they were delighted with the exhortation.
Notice the decision of the Council of Jerusalem? By what authority that they made a pronouncement? It was by the Holy Spirit, and by US--the authority of Jerusalem as a council made up of Apostles in their bishropic role. And hence, when the Church was loosing their apostles due to martyrdom, it was necessary for other councils to form in dealing with matters that threatened the Church and which councils were bishops who were made so by the authority of the apostles. In their pronouncements of Church teaching and the power of the Holy Spirit, we have been able to make clear the Triunity of the Father, Son, and Holy Spirit and upon Christ's incarnation to ward off a great many heresies from Arianism, Nestorianism, and countless others. There may be biblical precidence, but the fact that heresies twist the scripture, formulate their own persuasive reasoning to gain a threat against harming the Church faithful, there still needs must exist a clear cut interpretation authority. When abortion was made legal, when issues concerning cloning came out, the Catholic Church has made it clear what the high road to take while many denominations drag their feet and make judgemental errors like the Southern Baptists in their 1971 and 1974 resolutions supporting abortion. Even the most conservative councils of Protestant ecclesiastic forms have no authority when pronouncing its "affirmation."
In all due respect..I am aware of and do appreciate the stance of authority taken by the Roman Catholic Church on the issues mentioned above ; but it wasn't my purpose here to discuss the supremacy of one denomination over another in matters of authority. The question here is what do we think of the ordination of Gay clergy..so apologies as I didn't intend to go down the rabbit trail and off topic in my post and won't do so now. My point was to simply answer the question given and say that we can read in scriptures that homosexuality was not, is, or should ever be an acceptable practice and especially not condoned by church leaders, and is something to be dealt with in all of our Christian churches(denominational or not) ..yes, by God-given authority.
