La influencia bíblica es mayor en la Edad Media o en la actualidad por qué​
Step2247 [10]

Answer:

No entiendo bien a que te refieres con influencia bíblica, pero si te refieres a la iglesia en general, por decirlo así es mayor en la Edad Media

Explanation:

En esos tiempos la Iglesia tenía mayor poder, después pasó el tiempo y la gente empezó a no sólo llevarse de lo que ellos decían , si no a tener criterio propio y pensar por su cuenta, a razonar por ellos mismos, y al no llevarse sólo de lo que la Iglesia decía esta fue perdiendo poder.

Slav-nsk [51]

That's why when determining a position you would say that something is 40 degrees north and 74 degrees west, and this exact position would point to New York City. The first number is how north above the equator it is and the second number how much west from Greenwich it is. </span>
