This book explores the scientific method of the number one hundred and fifty-three, which was applied by Jesus Christ to the catching of one hundred and fifty-three large fish by the Apostles. Every Word of Jesus Christ cannot be meaningless and about nothing, but also a catch according to His Word. A number is a mathematical unit that can be obtained from other numbers of lesser value by adding them. A certain event enclosed in a certain numerical value or in a certain numerical frame carries within itself a certain numerical completeness of this event, which is subject to research.
