The position of a clause-modifying adverbial phrase

In the year 228, four years after Ardashir took power, when Mani was about thirteen years-old, a Parthian prince from the former Seleucid capital, Seleucia (a few miles from Ctesiphon), rose up against Ardashir but was cut down. It was said that just after this, Mani had a revelation from God, a command to leave the religious community to which he belonged. God, it was said, told him that he did not belong in that community and told him to keep aloof from impurity and because of his youth that he should avoid proclaiming his revelation publicly.

I'd like to know I can rephrase the underlined phrase to the following without the meaning change.
?and that because of his youth, he should avoid proclaiming his revelation publicly.

Thank you in advance for your help.
