The real Angel of God.
Angel Gabriel speaks to the Virgin Mary - Luke. 1-
31- And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.
32- He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:
33- And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
And then, announced to the shepherds- Luke. 2: 10- And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
11- For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
After the Christ made man (disciple) responsible in many texts, and sent:
Go ye into the entire world, and preach

the Gospel to every creature, starting in Jerusalem.
And when the Apostles where imprisoned - Acts 5.19-21:
19- But the angel of the Lord by night opened the prison doors, and brought them forth, and said,
20- Go, stand and speak in the temple to the people all the words of this life.
21- And when they heard [that], they entered into the temple early in the morning, and taught.
It is confirmed when Cornelius has a vision of God’s Angel, He told him to find Peter to announce the Gospel - Acts. 10.
In these texts, it’s proven that the Angel has no authority to preach or form any religion, and the last one of God’s angels in the Bible was the one that brought Jesus Christ’s revelations to John,who wrote to the angel man (responsible) of the seven Churches, the events that where going to happen until the end of time - Revelation. 1. 1 to 20.
