No, this is most definitely not true.
The Christian Maronites and Sunnis are rallying around Hezbollah. They may not agree politically, but they all agree that Lebanon needs defending from The Enemy to the South, and that is Hezbollah';s sole purpose.
You think Israel cares about Christians and Sunnis? No. You think thise 2000-lb. bombs they droip can distinguish between sects? No.
In 1989 those Christian and Sunni factions agreed in the Taif Accords to maintain Hezbollah as an armed resistance movement, even as they agreed to disarm and disband their own militias, because they recognised the need to resist Israel and fight Israel's occupation of Lebanese land.
Nasrallah and the Christian President Aoun signed an association pact, and Hezbollah has gotten along just fine with Christian political parties in Lebanon.
What also "endeared" Hezbollah to Lebanon's Christians was Hezbollah's willingness to go to Syria and fight ISIL/ISIS and Al Qaeda, to keep them from ever threatening multi-ethnic Lebanon as they did the secular Assad regime.
But of course nothing will unite a population more than an existential threat from without. Every time Israel bombs Beirut, it brings all the factions together.
When Israel was bombing the Shia population in Southern Lebanon, Christians gave blood.
Christian group, Jnoud El Rab donates blood in Lebanon.
Commenting on their actions, a member of the Soldiers of God (Jnoud El Rab) told the Lebanon Mirror website:
"We may have significant political differences with the party (hezbollah), but we will not be a dagger in their back. We are the children of one country and family, and blood will never turn into water."
