Can I disagree to the point that all false doctrine should be condemned to the point of excommunication from the church? Not to me.We will have to agree to disagree.I do not think anyone who proclaims to teach the Word of God should be a false teacher.They should only preach the true word of God.
Rom 14:1 Him that is weak in the faith receive ye, but not to doubtful disputations.
Rom 14:2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
Rom 14:3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Should I have nothing to do with my brethren in the Catholic church I came out of, because I certainly do no longer believe their doctrines?
Rom 14:5 One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
Rom 14:6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
What of those sweet brethren among us that do not believe in OSAS? Are they false brethren or just professing and understanding scripture different than me? Which is false? those believing in receiving the Holy Spirit today exhibited by speaking in tongues, or them that are Baptist believing gifts are done away with such as 1 Cor 13:8? Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
Maybe I'm just misunderstanding you.
