John 6:53-56

⁵³Then Jesus said to them, Truly I say to you, If you do not take the flesh of the Son of man for food, and if you do not take his blood for drink, you have no life in you.

⁵⁴He who takes my flesh for food and my blood for drink has eternal life: and I will take him up from the dead at the last day.

⁵⁵My flesh is true food and my blood is true drink.

⁵⁶He who takes my flesh for food and my blood for drink is in me and I in him.
