I just found on the SDA Official website the SDA attitude to other christian groups and their attitude to apostates. Some of you might be thinking Im preaching here but nothing could be farther from the truth in some areas I strongly disagree with SDA doctrine like the investigative doctrine and 1844
SDA attitude to other christians. From the official website
We recognize those agencies that lift up Christ before men as part of the divine plan for evangelization of the world and we hold in high esteem christian men and women in other communions who are engaged in winning souls to Christ.
SDA attitude to Apostates.
We recognize that true religion is based on conscience and conviction.It is therefore to be our constant purpose that no selfish interest or temporal advantage shall draw any person to our communion and that no tie shall hold any mamber save the belief and conviction that in this way the true connection with Christ is found. If a change of conviction leads a member of our church to feel no longer in harmony with SDA faith and practice we recognize not only the right but the responsibility of that member to change, without opprobrium, religious affilliation in accord with belief. We expect other religious bodies to respond in the same spirit of religious liberty.
