Entering Through The Door

Qui non intrat per ostium. Quia sicut per ostium intratur in domum, ita per principia cujuslibet veritatis intratur in scientiam veritatis illius, et per principia fidei intratur in scientiam fidei, quae est de credibilibus : sicut sunt articuli fidei. Si ostium est, compingamus illud tabulis cedrinis, hoc est, principiis imputribilis veritatis, quae numquam excidunt: quia cedrus est imputribilis. Ideo praecepit Dominus, Sument de sanguine ejus, scilicet agni, et ponent super utrumque postem, et in superliminaribus domorum in quibus comedent illum. Quia principia fidei sunt de passione, et superliminaria sunt de deitate: quia fere omnia principia fidei sunt, per quae vere intratur in Christianam religionem, vel de passione, vel de deitate Christi. Scribes ea, scilicet mandata, in limine et ostiis domus tuae. Quia observatio mandatorum nulla est quae non principiis fidei confirmatur.. Sanctus Albertus Magnus, Commentarium in Joannem, Caput X Source: Here, p185

He who does not enter through the door... 1 Because as a house is entered through the door, so through the principles of the truth one enters into the knowledge of the truth, and through the principles of faith one enters into the knowledge of the faith, which concerns things to be believed, which are the articles of the faith. 'If a door, let us fashion there boards of cedar', 2 that is, the principles of incorruptible truth, which never decay, because cedar is incorruptible. Therefore the Lord commands: 'Let them take up the blood,' that is of the lamb, 'and place it on both doorposts and on the lintels of the house in which they eat.' 3 Because the principles of the faith concern the Passion, and the lintels Godhood, since almost all the principles of the faith, though which one enters into the Christian religion, are either of the Passion or of the Deity of Christ. 'Write these things,' that is the commandments, 'on the threshold and the doors of your house.' 4 There is no keeping of the commandments which the principles of the faith do not confirm.
