Yes. The SBC website explaines that the SBC Faith and Message is a confessional (not creedal) and represents the "general consensus" and beliefs held by most SBC churches.not believe in OSAS?
The SBC does not dictate to churches what they require members to believe, but expreses a common consensus of belief among churches.
In short, if your SBC church is fine with you not believing OSAS then there is mo issue with the Convention.
I know several persons who are SBC and outspoken against OSAS. Their church does not require them to affirm the doctrine to be a member, but leaves this to religious liberty.
Anyone who says you cannot be SBC and reject any one point of the SBC Faith and Message does not understand the nature of the SBC.
That said, I doubt your church could reject the doctrine and be SBC.
