Quote by Henry Brooks Adams
I tell you the solemn truth, that the doctrine of the Trinity is not so difficult to accept for a working proposition as any one of the axioms of physics.
Summary
This quote suggests that accepting the concept of the Trinity, a theological doctrine that posits God as being in three persons (the Father, the Son, and the Holy Spirit), is no more challenging than accepting the axioms of physics in terms of practicality. It implies that despite its complexity, the idea of the Trinity can be embraced and understood in a practical sense, much like the scientific principles that underpin the physical world.
