Philosophically speaking when two or more things have something in common they have the same ancestor.
The frequency of commonalities, as those shown in religious practices, confirms derivation from the same 'mother'.
Behaviour and thought patterns are not accidental when closely aligned.
They do, however, deviate somewhat due to distance, time, language and environment.
It is through linguistics that the test can be best applied.
Languages with commonalities and ancestral parents enable grouping into families, for example Indo-European that incorporates languages from outside Europe, such as Sanskrit.
Their common links trace back to the Middle East.
Religion is born of philosophy because ideas from leaders gather followers.
Such require a vehicle to carry them forth and that is language.
It is no surprise, therefore, that these two systems emerged together and that terms of worship have common links.
My interest followed my reincarnation and knowledge that religious teaching is wrong.
There is no heaven or hell and yet these eternal destinations are the rocks on which religions stand.
The first is a reward for dedication to the nominated gods while the second invokes fear to prevent straying.
There is only one God and that is the Spirit of the Universe and the Creator of all things, including religion.
While it allowed mankind to have free will it directed their drive to invent false gods and worship along with the construction of shrines.
It did this for a reason as explained in the Old Testament.
The origin of modern faiths stand in the ruins and iconography of Babylon.
Looking at just two versions, Christianity and Muslim, the commonalities cannot be put down to anything other than a common ancestor that is Islam.
Here is a short list of some of their commonalities: A) They promote heaven and hell as destinations for the dead B) Their chiefs wear long robes C) They also use circular head caps D) They are dedicated to a monotheistic god although they believe in other gods, such as Satan, etc.
E) They use buildings, such as temples, churches or mosques, for masses F) The priest or omar preaches from an elevated platform or pulpit G) They have patriarchal ideals that discriminate against women, although Christians less so.
H) They preach about sin and forgive them in order to keep the faithful returning I) They inter the dead in the belief of a resurrection J) Their prophets reign in heaven and are spokesmen for their Gods.
K) They employ books for credibility and brainwash the young into acceptance L) They have feast days and festivals as special times of worship and fasting, i.
e.
Lent and Ramadan M) Their idols are instruments of worship to impress followers N) They employ violence towards non-believers, but Christianity has moderated O) The chief, Omar or Pope, claims he can send people to heaven or hell P) Their headquarters, Roma and Mecca, are in religious dominated countries Q) While they claim Jerusalem as their holiest site.
R) Followers are forbidden to explore other faiths S) They use commandments supposedly given by God through a prophet T) Old Testament writings is the base for their religions.
U) Sex is controlled through religious marriage V) Children are brainwashed from birth While these commonalities are shared by other faiths as well, for example that of Judaism, it allows for the conclusion that they have emerged from a common mother, which is Islam.
Some may argue that these things could emerge through separate invention but the chances of so many likenesses makes that impossible.
