yes, the basics are simple

“It is certain that, in one point, all nations of the earth and all religions agree. All believe in a God. The things in which they disgrace are the redundancies annexed to that belief; and therefore, if ever an universal religion should prevail, it will not be believing anything new, but in getting rid of redundancies, and believing as man believed at first.45 Adam, if ever there was such a man, was created a Deist.” Thomas Paine

This is deism.

Santana Dharma says all paths lead us to the same Truth. Our duty is to follow faithfully the path chosen by us ( or the caste into which we are born) for the larger good of humanity.
What the Abrahamic religions say is the same as Sanatan except that they are limited in their outlook.
In the beginning was the Word = Om is the Pranava.
God made man after his own image = The original Adam was Ardhanari .
The Tower of Babel = The veil of Maya over Creation.
Sanatan goes further than this when it talks of the four Yugas , and reincarnation ( retribution for past Karma)
Sanatanis must however remember that today’s antagonists were in previous births Sanatanis themselves who failed to carry out their assigned duties and are at the receiving end of what they perceive as discrimination while the erstwhile detractors are today’s ‘oppressed’.
Read about how AdiShankara , Ramanuja and Ramakrishna Paramahamsa realized these truths.
