al_c ... convert to Catholicism.
You made some good points on converts - probably true. However the issue shouldn't be converting to a church or denomination, or a religion in the case of Judaism, but to do as the resurrected Lord Jesus Christ commissioned the apostle Paul, "To open their eyes, and to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me." (Acts 26:18) We should trust God and believe in His Son and in His Word. That's what we should be about so we can look back and see "how ye turned to God from idols to serve the living and true God." (1Thess. 1:9) We don't need to convert people to a specific church to do and believe this.
