If we truly live the two Greatest Commandments the "doctrinal issues" will take care of themselves.
I certainly agree that all things must be done in the spirit of love so please don't construe my next comment as a personal attack.
If the Roman Catholic Church really teaches your viewpoint, then I do not see how, in light of the Inquisitions, Crusades and other persecutions of "heretics", it can then - when such actions are no longer "legal" - warn everybody to "let the doctrinal issues take care of themselves" with a straight face. It also contradicts Scriptural instructions for the man/woman of God to to be able to teach, preach the word, be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine (II Tim. 4:2) and hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it (Titus 1:9). We are also urged in Jude 1:3, "to contend for the faith that was once for all entrusted to Gods holy people". That is what most of us here are doing - contending for the faith, the faith that has been entrusted to ALL God's people so that souls are won to the Lord in the Biblical truth.
