Regarding the view of Bible scholar Prof. Benjamin Sommer

Hello Rabbi,
An article about Prof. Benjamin Sommer was recently published, which tells a little about his teachings regarding faith. There he says:

“There is a divine command, certainly there is, and it was given in the great revelation at Mount Sinai – but this command did not include any commandments. It only required us, the Jews, to love God and worship Him. How do we do this? To the giving of the commandment were added three points that God left for us – and for thousands of years we, the human race, have fulfilled these three points, chosen and formulated the way in which we worship Him, and these are the Torah and the commandments that we know.”
“God actually dictated to us – in that great revelation – one word: ‘Love me.’ How do we love Him? For example, by putting on strips, parchment, and skins (tefillin). For example, by abstaining from cooking milk and meat together. These are commandments that we have decided upon as a Jewish collective for thousands of years.”

On the surface, this sounds like nonsense to me, but I wanted to check with you to see if maybe there's some depth here that I'm missing?
Best regards,
