But Indian philosophy taught this Trinitarian doctrine long before Christianity.

The Catholic Answers

It did not. In the Vedic philosophy there are traces of a trinity, but not of the Trinity. The idea of Father, Son, and Holy Ghost is not to be found in it. That philosophy taught a pantheistic notion, all things being a kind of emanation from God to be reabsorbed into Him. It has no distinction such as ours between the Creator and the creature, and Brahma, Vishnu, and Siva bear no real resemblance whatever to the Christian doctrine of three divine and equal personalities sharing the one divine nature. The Indian notion no more resembles the Christian doctrine than does the hegelian Thesis, Antithesis, and Synthesis. You might just as well try to account for the notion of the Trinity from any notion of triplicity wherever it occurs.
