Erlöser vs Helfer
helper
'der Helfer' and 'der Erlöser' can both refer to a person who helps someone in a difficult situation. 'Helfer' is the normal and neutral word. A 'Helfer' supports someone with a task or a problem, even if the situation is not very serious. 'Erlöser' is much stronger. In a figurative sense, an 'Erlöser' frees someone from a very difficult or desperate situation. The words can be confused because both sound positive. But 'Erlöser' sounds grand, emotional, or solemn. For normal everyday help, 'Helfer' is almost always more natural.
Erlöser
Als der Arzt endlich kam, wirkte er für die Familie wie ein Erlöser.
When the doctor finally arrived, he seemed like a savior to the family.
Helfer
Beim Umzug waren zwei Helfer aus der Nachbarschaft dabei.
Two helpers from the neighborhood helped with the move.
