I do believe from what i have read in Gods written word we find that in Noahs day--it proved beyond the shadow of a doubt that all roads do not lead to God, but one road leads to God. Noah a servant of( YHWH) Jehovah-- as was Moses,David,Isaiah,Job,Lot,Daniel, etc-- every one of them served the true God--they all served YHWH(Jehovah) a single being God. So did Jesus-rev 3:12. 1 cor 15:24-28.
Without a single doubt in Gods written word,God never had more than a single religion that was his.Jesus came and started a single religion, united in love and peace worldwide.
The name Jesus taught his true followwers at John 17:6 is YHWH(Jehovah) and at John 17:1-6--Jesus said that his Father( the one who sent him-John 5:30) is the only true God. Paul taught the same at 1 cor 8:6) the trinity translations have been altered to fit catholocism council false teachings.
