Oh my goodness, I do hope you are not saying that you actually take the consecrated host out of the church without the pastor’s knowledge and permission. That may in fact constitute a serious sin.
My father could not leave the house for a long time due to prolonged illness. My mom called the parish office, and an Extraordinary Minister of Holy Communion (EMHC) came to the house DAILY for weeks.
It is not complicated for someone who is home-bound for ANY reason to get help from the parish while following the rules set forth by Holy Mother Church. To take matters is our own hands is dangerous to our souls.
Are you trying to isolate those in need from their parish by taking things into your own hands?
Or are you trying to bring the Blessed Sacrament to those who are outside the Church or are not allowed to receive Holy Communion licitly.
I cannot imagine a valid reason to go behind the pastor’s back like that. Bad idea for everyone involved.
