No absolute perfection
Christian perfection therefore does not imply (as some men seem to have imagined) an exemption either from ignorance or mistake, or infirmities or temptations. Indeed it is only another term for holiness. They are two names for the same thing. Thus, everyone who is holy is, in the Scripture sense, perfect. Yet we may, lastly, observe that neither in this respect is there any absolute perfection on earth. There is no perfection of degrees, as it is termed, none which does not admit of a continual increase. So that how much soever any man has attained, or in how high a degree soever he is perfect, he has still need to grow in grace, and daily to advance in the knowledge and love of God his Savior (2 Peter 3:18).

There is no perfection of degrees, as it is termed; none which does not admit of a continual increase.
