Father stokes tells Rick, "God hates violence." Any first year seminary students who knows the Old Testimont can clearly explain God's wrath and violence. Think Sodom & Gomorrah for example.
On the path away from Terminus, Rick and Daryl whisper to each other that the group is being followed. Later (despite knowing Gabriel wasn't following them), the whole group is relaxed inside the church. Daryl and Carol just leave. Bob steps outside, oblivious to any danger. This would mean that Rick and Daryl not only never told the others about being followed, but apparently forgot all about it.
