I am a Ruling Elder in the PCA and our local church has had some significant issues with heavily involved, communing non-members that continue to refuse to become members. They are Reformed-ish Baptists and don't want to become members for that reason, even though it has been explained multiple times that the PCA's membership vows mention nothing of infant baptism and are purely evangelical. They have been members of other evangelical churches in the past, so they currently are able to take part in The Lord's Supper. Like I mentioned previously, they are very involved in the church (multiple Bible studies, Sunday School, group activities) but obstinately refuse to become members. Any thoughts, particularly from NAPARC officers?
