On the divine side the call has become a command; on the human, the free impulse of love has become an act of submission, by which life eternal will be earned.
At the bottom of it all is the antinome of law and love.

Under the reign of law we are the mercenaries of God, bound down to an irksome task, but paid a hundred-fold, and with an indisputable right to our wages.
Under the rule of love we are the sons of God, and coworkers with him; we give ourselves to him without bargaining and without expectation; we follow Jesus, not because this is well, but because we can do no otherwise, because we feel that he has loved us and we love him in our turn.

An inward flame draws us irresistibly toward him: _Et Spiritus et Sponsa dicunt: Veni_.
It is necessary to dwell a little on the antithesis between these two Rules.

That of 1210 alone is truly Franciscan; that of 1223 is indirectly the work of the Church, endeavoring to assimilate with herself the new movement, which with one touch she transforms and turns wholly from its original purpose.
That of 1221 marks an intermediate stage.

It is the clash of two principles, or rather of two spirits; they approach, they touch, but they are not merged in one another; here and there is a mixture, but nowhere combination; we can separate the divers elements without difficulty.
