Well, yes and no. One may be 'born again' but lose one's faith. Scripture is clear on this. "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." - Matthew 7:21. The most important form of veneration of the saints is "imitating" the saints, as Paul commands us to do (1 Cor. 4:16). To Catholics, those that have fought the good fight and "endure unto the end, the same shall be saved" (Matthew 24:13). Those the Church proclaim to be saints, have done just that.
Are you saying that one can lose his salvation? Yes we are suppose to live up to the Saint title but none the less I go back to my original point. The scripture calls all born again believers Saints. Argue from any direction or add little tid bits to it but bottom line, it is true.
