innitency

But such a Faith is required to bring us within the Covenant as is an Affiance or resting innitency, or resting of the soul upon Jesus Christ exhibited in the promise for life and salvation, expressed in Isaiah by trusting in the Lord, and staying upon the name of God, when we sit in darkenesse and see no light.

Rothwell, page 19

The Formal Cause, which doth straiten the general nature of Faith, and distinguish true Saving Faith from all other Faiths (forma vel aliquid formae analogum ponitur differentiae loco) in which may be Notitia & Assensus, is Fiducial receiving of Christ offered by God in the Promises of the Gospel. In which are two things formally constitutive of Saving Faith. […] 2. Innitency, recumbency of soul upon a Christ received, entrusting him entirely with, and committing to him the care of Soul and salvation, staying the soul upon him, leaning upon the beloved, rouling the soul upon him, resting with whole weight upon him, as faithful, able, loving: and this is truly fiducia; this is truly Credere in Christum, To believe in or upon Christ; more than Credere Christum, & Christo, to believe a Christ (that he is) and to believe Christ (or his word.)
