Does the Bible say that Jesus is the Almighty?

No.  That is a man-made teaching, one which is also non-biblical. The word “Almighty” is found in 9 passages and none claim Jesus to be Almighty God!

2Co 6:18  And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.

Rev 1:8  I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.

Rev 4:8  And the four beasts had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, which was, and is, and is to come.

Rev 11:17  Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
