Matt 5:20 or enter you won't., page-11

That's right.
He taught JUSTIFICATION by faith alone - not of works.
Eph 2:8-9, Gal 2:16, Rom 3:24-28, Rom 4:5-8, Titus 3:5, Eph 1:13
He taught WORKS are subject to eternal rewards/loss.
1 Cor 3:10-15, 2 Cor 5:10, Rom 14:10.
..
If you believe he taught that JUSTIFICATION requires works, please list his verses.
