2773. 'Your only one, whom you love' means the 'only one' in the entire universe by which He was to save the human race. This is clear from the meaning of 'only' as the only one, indeed the only one in the entire universe, for the subject is the Lord who alone as to His whole Human became God, that is, became Divine.

2630. 'Isaac' means the Divine Rational. This is clear from what has been stated already about Abraham, Isaac, and Jacob in 1893, 2066, 2083, to the effect that 'Abraham' represents the Lord's Supreme Divine, 'Isaac' the Divine Rational, and 'Jacob' His Divine Natural, as will also be clear from what comes later on where Isaac is the subject.
