And we believe and are sure that thou art that Christ, the Son of the living God.
And we believe and are sure, х heemeis (G2249) pepisteukamen (G4100) kai (G2532) egnookamen (G1097)] - 'And we have believed and know.' The 'we' is emphatic: 'Whatever may be the case with others, we' etc.
That thou art that Christ, х ho (G3588) Christos (G5547)] - rather, 'the Christ.'
The Son of the living God. (See the note at Matthew 16:6.) Peter seems to have added this not merely-probably not so much-as an assurance to His Lord of his heart's belief in Him, as for the purpose of fortifying himself and his faithful brethren against that recoil from those harsh statements of His which he was probably struggling against with difficulty at that moment.
