Your issue is not with birth control… it’s with the authority of the church.
Jesus proclaimed all foods clean; do you allow the Church to tell you what to eat?
Or consider this explanation (NASB translation)
Romans 14
Principles of Conscience
1Now (A)accept the one who is (B)weak in faith, but not for the purpose of passing judgment on his opinions.
2(C)One person has faith that he may eat all things, but he who is (D)weak eats vegetables only.
3The one who eats is not to (E)regard with contempt the one who does not eat, and the one who does not eat is not to (F)judge the one who eats, for God has (G)accepted him.
4(H)Who are you to judge the servant of another? To his own master he stands or falls; and he will stand, for the Lord is able to make him stand.

When we so narrowly work to define the “Law” such that it touches on birth control, it shows either a lack of understanding of passages like this, or a belief that the average parishioner cannot understand passages like this.
I know people who are concerned about living a life of drunkedness. There are passages of the Bible that lead to that concern. So they don’t drink wine. I do not offend them by offering them wine in my home - nor do I offend others who do not hold this belief by refusing to offer it.
There may be those who need both the unitive act and the lack of children. I can see from the passage above that this is between them and God. If they choose a barrier ABC, its none of my business.
