On what basis though is the Father able to redeem us, as there must still be a basis for salvation, to allow Him to stay Holy while forgiving sinners?
The Father does not face inability, so your question is not valid.
The basis that mankind is forgiven is Christ's sacrifice.
The basis that we are forgiven repentance - turning from sin and to Christ.
Scripture tells us that the Father forgives based on repentance. This is further explained as turning from ourselves and to Him in faith.
Ultimately our salvation is dependent on recreation (dying to sin and being made alive in Christ, being made a new creation in Christ, being born of the Spirit).
My point, however, was not to debate this but simply to point out that there are many Baotist churches that share my belief. Rather than trusting in reformed Roman Catholic doctrine many of us simply trust God's Word.
