And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. (Matthew 19:4-6)
And he said, That which cometh out of the man, that defileth the man. For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man. (Mark 7:20-23)
And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life. (Revelation 21:27)
Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. (Revelation 22:14-15)
God made man and women distinctively different yet uniquely compatible and complementary, and only joined them together in marriage - as again the Lord Jesus Himself specified, (Mt. 19:4–6) and Scripture only condemns homosexual relations wherever they are manifestly dealt with (extensive examination of prohomosexual polemics with refutations, by the grace of God). And which have been tragically primarily responsible for approx. 80% of new HIV cases among men and over 700,000 American deaths (although such is not even the decisive reason why homosexual relations are wrong). et there is still room at the cross for all who will come to God in repentance and faith, and trust in the Divine Son of God sent by the Father, the risen Lord Jesus, to save them on His account, by His sinless shed blood, and thus be baptized and live for Him. (Acts 10:36-47) Thanks be to God.
But opposing homosexual unions is somewhat problematic for a church that teaches required clerical celibacy as the norm, as well as other distinctive Catholic teachings that are not manifest in the only wholly inspired substantive authoritative record of what the NT church believed (which is Scripture, in particular Acts through Revelation, which best shows how the NT church understood the gospels)
Right there is our Human Condition!
