Non as it is a pagan symbol:-
"One of the oldest amuletic signs in the world, perhaps even the oldest, is the CROSS, that is to say the figure which is made by two straight lines which bisect each other at right angles +. This is what in commonly understood by the word "cross," and not the single wooden pillar or pole to which malefactors condemned to death were tied, and which is spoken of by some writers as the crux simplex. It was at one time believed by many writers on ecclesiastical symbols, relics, etc., that the cross was entirely of Christian origin, but such is not the case, for it was in use among the pagan peoples of Eastern Asia and Europe many centuries before the death of Christ. That the pagan cross symbolised something quite different from that which the Christian cross commemorated hardly needs to be said. But judging by what we think we know symbolism of the pagan cross we are justified regarding it as a forerunner of the Christian cross. . . ."-'Amulets and Superstitions' by E.A. Wallis Budge p.336
"CROSS "The shape of the [two-beamed cross] had its origin in ancient Chaldea, and was used as a symbol of the god Tammuz (being in the shape mystic Tau, the initial of his name) in that country and in adjacent lands, including Egypt. By the middle of the 3rd cent, A.D. the churches had either departed from, or had travestied, certain doctrines of the Christian faith. In order to increase the prestige of the apostate ecclesiastical system pagans were received into the churches apart from regeneration by faith, and were permitted largely to retain their pagan signs and symbols. Hence the Tau or T, in its most frequent form, with the crosspiece lowered, was adopted to stand for the cross of Christ"-'An Expository Dictionary of New Testament Words' (London, 1962), W.E. Vine, p.256
"The well-known T-shaped cross was in use in pagan lands long before Christianity, as a representation of the male member, and also at the same time of the 'tree' on which the god (Attis or Adonis or Krishna or whoever it might be) was crucified; and the same symbol combined with the oval (or yoni) formed the Crux Ansata [T under O] of the old Egyptian ritual-a figure which is today sold in Cairo as a potent charm, and confessedly indicates the conjunction of the two sexes in one design."-'The Origins of Pagan and Christian Beliefs by Edward Carpenter p.183
