Replying to your last question first. Ina perfect world; absolutely

But we donât live in a perfect world. Faith is and MUST come from God Himself.
You should live your [our] fait fully and publically; teach and answer questions when they arrive. And pray that is God time and Godâs WAY; youâll be guided by the HS to do what God would have you do His Will.
If memory serves from my time in YORK Pa., Quakers do not avail themselves of modern means of communication; which GREATLY limits their access to the TRUTH. I could envision them not knowing because they have NOT had an opportunity to know Christ and HIS Church /Faith. Thus BOD is a possibility.
However IF they have a REAL Bible; they are likely at risk. Sacraments Like Baptism from John 3:5; Penance from John 20:19-23; Eucharist from FIVE different NT Authors and Christ Himself; notably in John chapter six; Confirmation from the Pentocost account of John 20, and the last Rites from James 5:14 are clear enougn to at least raise reasonable questions. THIS IS A HIGH RISK factor.
BUT itâs Godâs judgment call. Holy He can determine and judge motive and compare it to REAL Opportunity for the truth.
Keep praying for them and be ready if and when an opportunity presents itself.
God Bless you and them!
