Or do you believe they’re too different, or even maybe that the introspective type Zen meditation is anethema of Christianity…

Buddhism, from which what is termed ‘Zen’ was codified, is quite varied, as is the practice of Zen. There are Zen Christians out there, and Zen Taoists, even Zen pagans and Zen ancestor worshippers. I believe Zen is the seed of Buddhism, but not necessarily one with it.
I also think Christian Mystics like St. John of the Cross and St. Teresa of Avila, and even the Islamic Sufi Mystics applied aspects of Zen before the Buddhist terminology even made it’s way to Europe and North Africa.
