大乘起信論裂網疏 2.4

2.4

顯示實義以除疑、對治邪執以去執，即是起信。分別修行正道相，即是紹佛種也。

Revealing the true meaning is to eliminate doubts; remedying wrong attachments is to remove clingings; these are precisely the awakening of faith. Distinguishing the marks of practicing the correct path is precisely continuing the Buddha lineage.
