Would, or even COULD Catholics go for any length of time without praying to Mary or even thinking about her?
Jeremiah 29:13 You shall seek me, and shall find me: when you shall seek me with all your heart.
I would dare any Catholic to spend a month praying only to God, not Mary, not any saints, not even telling anyone else they're doing it and asking them to pray for them, just them and the Father, asking the Holy Spirit to guide them, seeking God alone with their whole heart, and see just where the Father leads them.
Read ONLY Scripture and nothing else. I would challenge them to trust ONLY God.
Im thinking you will get no takers on that.
A worthy exercise, imho.
