Dear Polycarp1,
No thats the Christian opinion based on what the Bible says. That should be your opinion too if you are an Anglican. See Lambeth 1.10. And indeed the marriage union of a man and a woman is a rite or secondary sacrament.
Look here is Lambeth 1.10 and just for you to be able to test who speaks the truth and those who are self pontificating Anglicans who might believe neither the Bible nor their churchs position.
commends to the Church the subsection report on human sexuality;
in view of the teaching of Scripture, upholds faithfulness in marriage between a man and a woman in lifelong union, and believes that abstinence is right for those who are not called to marriage;
recognises that there are among us persons who experience themselves as having a homosexual orientation. Many of these are members of the Church and are seeking the pastoral care, moral direction of the Church, and God's transforming power for the living of their lives and the ordering of relationships. We commit ourselves to listen to the experience of homosexual persons and we wish to assure them that they are loved by God and that all baptised, believing and faithful persons, regardless of sexual orientation, are full members of the Body of Christ;
while rejecting homosexual practice as incompatible with Scripture, calls on all our people to minister pastorally and sensitively to all irrespective of sexual orientation and to condemn irrational fear of homosexuals, violence within marriage and any trivialisation and commercialisation of sex;
cannot advise the legitimising or blessing of same sex unions nor ordaining those involved in same gender unions;
