Taiwanese church leaders have been meeting Chinese Communist Party political organs for years, raising fresh worry that religion is being used as a channel for Beijing's influence in Taiwan.

• A Taiwanese pastors' delegation began traveling to China in 2011 and met the head of China's religious affairs bureau, a deputy chief of the CCP's United Front Work Department, and a deputy head of the Taiwan Affairs Office.
• Chinese officials openly told the visitors that churches on both sides should help achieve "the great rejuvenation of the Chinese nation" — Beijing's core political slogan.
• The traffic then reversed: a delegation of about 90 people from China's state-approved Protestant body came to Taiwan to meet pastors across denominations.
• That state church system is bound by its own charter to support Communist Party leadership and make Christianity more Chinese.
• The story surfaced after a Taipei church drew criticism for calling Xi Jinping by an affectionate nickname and echoing the same rejuvenation slogan in its bulletin.

Outlook: Expect more scrutiny in Taiwan of church-to-church ties with China as election-season worries about United Front influence grow.
