Jesus' disciples must have looked much like some of the members of the SPD in the Bundestag on Wednesday when he turned water into wine at the wedding in Cana.

It borders on a political miracle that after 16 years of abstinence the Social Democrats are again appointing the Federal Chancellor of the Federal Republic of Germany.

Half a year ago, hardly anyone in the party had expected it.

But Scholz took the chance he didn't have.

His self-belief and perseverance have now been rewarded with the most powerful political office the republic has to bestow.

In front of the man who led the SPD out of the bondage of the grand coalition and the "crap" of the opposition, even those who did not want him as party chairman and only let him run for chancellor because they saw it as hopeless are bowing.

But how long will the miracle last?

How close is the coalition to its Chancellor?

Despite the harmony and the spirit of optimism that should prevail in the traffic light coalition according to its own account, Scholz was already missing at least 15 votes in the election for Chancellor.

Kühnert claims that the dissenters did not come from the ranks of the SPD.

But he can't prove it.

And the lack of support from the FDP and the Greens would raise the question of how close this coalition is to its Chancellor on day one.

But it will depend on whether Scholz can “move something great”, as he attested to his predecessor.

The domestic and foreign policy challenges facing the new Chancellor and his government from today will provide ample opportunity to do so.

Scholz does not rely on divine assistance, as his renouncement of religious affirmation when taking the oath showed.

After Schröder, he is only the second of nine Federal Chancellors to have made a purely secular vow.

Seven of his ministers did the same.

In no case was one surprised.
