..the Reformation Church of England did not view basic issues of Christian morality as among those issues which could be considered adiaphora. We can see this in Article VII. The second half of this Article states:
Although the law given from God by Moses, as touching ceremonies and rites, do not bind Christian men, nor the civil precepts thereof ought of necessity to be received in any commonwealth; yet, notwithstanding, no Christian man whatsoever is free from the obedience of the commandments which are called moral.
What this statement shows is that in line with the teaching of the New Testament, the 16th century Church of England held that on moral matters (including matters of sexual morality) the teaching of the Old Testament, summarised in the Ten Commandments and the twin command to love God and neighbour was still in force.13 Consequently such matters could not be seen as adiaphora.
Furthermore, even in regard to matters which were adiaphora the Reformation Church of England did not hold that individual Christians were simply free to do whatever they saw fit. This can be seen in Article XXXIV. This reads as follows:
It is not necessary that traditions and ceremonies be in all places one or utterly alike; for at all times they have been diverse, and may be changed according to the diversity of countries, times, and men’s manners, so that nothing be ordained against God’s word.
Whosoever through his private judgement willingly and purposely doth openly break the traditions and ceremonies of the Church which be not repugnant to the word of God, and be ordained and approved by common authority, ought to be rebuked openly that other may fear to do the like, as he that offendeth against the common order of the Church, and hurteth the authority of the magistrate, and woundeth the conscience of the weak brethren

Conclusion
What we have seen in this paper is that it does make sense to talk about things that are adiaphora.
However, matters on which there are binding commands or prohibitions contained in Scripture (including in the area of sexual morality) do not come under the category of adiaphora.
Furthermore, even with regard to those matters which do come into this category we are not free to do whatever we want. Our exercise of Christian freedom either as individuals or as churches always has to be qualified by an awareness of the implications of our choices, and in particular what impact they will have on the welfare of our neighbours, our obedience to church order and state law and the well-being of the Church as a whole.
The New Testament is clear that sexual purity is a core requirement of the Christian life.
“But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people. Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God.” Ephesians 5:3-5
