• Viking invasions: Focused on raids and settlements, not religious spread of these two.
• Barbarian invasions: Led to political changes, not direct religious spread of these Christian branches.
• Monasticism: Monasteries preserved and spread Christian teachings (including both Roman Catholic and Orthodox traditions) through missionary work, scriptural copying, and cultural influence.
