“Mk:16:16: “He that believeth and is baptized shall be saved: but he that believeth not shall he condemned.”
Your church interprets “believeth” in a universal way. It does not mean believe on the Lord Jesus Christ, exclusively. Based on the Lumen Gentium, sincere belief on a coke bottle fallen from the sky is enough to get you to wherever or the sincere belief of the Heaven’s Gate cult waiting for the appearance of Comet Hale-Bopp in 1997 got them eternal life somewhere.
It just depends on whoever you sincerely believe God is, could be obama!
In the words of Lumen Gentium, adopted at Vatican II:
“But the plan of salvation also includes those who acknowledge the Creator. In the first place amongst these there are the Mohamedans, who, professing to hold the faith of Abraham, along with us adore the one and merciful God, who on the last day will judge mankind.”
“The non-Christian may not be blamed for his ignorance of Christ and his Church; salvation is open to him also, if he seeks God sincerely and if he follows the commands of his conscience, for through this means the Holy Ghost acts upon all men; this divine action is not confined within the limited boundaries of the visible Church.”
The Holy Ghost acts IN mankind, not ON them, and only IN those who have the Lord Jesus Christ within.
