Quran 66:4 Is Jibreel عليه السلام An Angel?
Will try to get explanation from Hassan Sahab for more clarity in this matter.
Jibreel is a known word associated with Angel of God and has been prominently mentioned in different verses separately from other angels (emphasizing his importance). Therefore, it is a valid inference that if someone has been given such big titles as rasul, ruh ul qudus etc. in the context of bringing revelation to the Prophet and helping Prophets, Jibreel (AS) holds this status to perform this job. These titles commensurate with both name and status of Jibreel (AS) as mentioned in Quran.
To be honest I am satisfied with the response. The words have a historical context behind them which makes sense
