Much has been written on this subject of vital importance for the Church. A significant number of Christian scholars, such as renowned historians, theologians and all kinds of researchers committed to spreading the beginnings of the evangelizing mission that was granted by Christ to his disciples, have already expressed their points of view through their works, created from intense research, whose information was extracted from reliable sources, many of which reveal the beginning of the Christian faith and the emergence of the Church from the first centuries after the death, resurrection and ascension to heaven of the Redeemer. However, in this book the author intends to gather, in a succinct and clear manner, without excessive academic tone, to present to the most profane in the subject small details of the vastness of the immeasurable journey that the gospel of grace that the Savior of humanity proclaimed to those who were lost has traveled to this day.
