Correct.

¹⁶And Simon Peter answered and said, "Thou art the Christ, the Son of the living God." ¹⁷And Jesus answered and said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven. ¹⁸"And I also say to you that you are Peter (petros), and upon this rock (petra) I will build My church; and the gates of Hades shall not overpower it. Matthew 16:16, 18 (NAS)

God (Jesus' Father) had revealed to Peter that Jesus was "the Christ, the Son of the living God."  This is the "mass of rock" that Jesus' church would be built upon.

Jesus is described by Paul and by Peter as the "Mass of Rock" - "Petra":

Romans 9:33, referring to Jesus Christ, says:

"...just as it is written, "Behold, I lay in Zion a stone of stumbling and a rock (petra) of offense, and he who believes in Him will not be disappointed." Romans 9:33 (NAS)

1 Peter 2:4-8, referring to Jesus Christ, says:

"And coming to Him as to a living stone, rejected by men, but choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. For this is contained in Scripture: "Behold I lay in Zion a choice stone, a precious corner stone and he who believes in Him shall not be disappointed." This precious value, then, is for you who believe. But for those who disbelieve, "The stone which the builders rejected, this became the very corner stone, and, "A stone of stumbling and a rock (petra) of offense"; for they stumble because they are disobedient to the word, and to this doom they were also appointed." 1 Peter 2:4-8 (NAS)

In Hebrews 1:8, God calls His son Jesus "God".  How do you feel about Jesus being the Rock or cornerstone of His church?
